Composite Modeling of a Boat Transom in Ansys Composite Prep (ACP)

Okay, then I'm going to start with this boat model. This is just a generic geometry I took from the internet. It's a surface model, but the idea is to model this zone called the transom. It's where the motor and all the power of the motor is transmitted to the whole structure.

For the composite industry, it's important to have a structural analysis of this zone of the boat. Obviously, we are not going to simulate the entire boat. We are going to work only with a portion of it. I've made a cut, an arbitrary cut of the geometry in some place.

It's just a cut, and we've made some simplifications. When we are going to work in ACP to model composite materials, it's important to planify in advance where we are going to apply the reinforcement. We can do it either in the Space Claim or Discovery in the geometry stage, or we can do it in ACP.

But if we already know that we are going to apply our reinforcement, it's more useful, it's easier to do it in the geometry step. For example, I've made here... We know that this vertical surface is going to be connected to this other one.

That's why I divided my geometry into surfaces in order to apply a future reinforcement here. But maybe we are not sure of all the zones we need to apply reinforcement. But we can do it later in the other interface. We have some different zones. Here, all are surface bodies.

I've created these circles here to apply the motor load. And here, these rectangles in order to apply the motor thrust. From the geometry side, I guess that's a simple thing to do. And at the end, I applied some shared topology to connect the different body surfaces.

Then we are going to pass to the ACP. That's where the magic occurs. We are going to define all the composite structure. We are starting from the top and going to the end, defining everything we need. First, we have from the engineering data, we have the material.

For example, here, we have a unidirectional ply with these properties. And we are going to create a fabric with it. That means that here at this level, we have only the material definition. Then we can create one or more fabrics to be used in our model. For example, here, I created one.

But in this case, I assign a thickness of one. That means one millimeter in this model. For the fabric, I could say that's all. Then we can create not only fabrics, but also stackups. For example, if we buy from the supplier, we buy our already prepared stackup.

For example, one layer of fabric, one with an orientation of zero degrees. A second one with 30, 45, zero, and so on. Okay. So, I've created a seven layers stackup to define my composite structure. I could do it by this way, or I can create all the levels by each fabric.

But it will not be an efficient way to do it. But at the end, it's the same thing. Because when we're creating our model, we are assigning a layer element. At the end, we are going to assign each layer for each layer of the element. It's the same thing at the end.

But defining in this way is easier to configure the model. Then, the important thing when creating these models is to create a lot of element sets that are the same as the name selection. Because we have to create everything based on the name selection.

Because we have to create everything based on the name selection. Because we have to create everything based on the name selection. Because we have to create everything based on the name selection. Based on the name selection definitions.

For example, we have here an element set named "all elements," but we have a lot of them in order to define, for example, here a reinforcement. We have here exterior and the other, and something like that. We have several element sets.

Then, we have, for example, here several row sets that they are only coordinate systems. It's the same thing, but we use to define every layer of our composite structure. Then, the most important thing are the oriented selection sets. That's the real surface. That's the real surface.

That's the real surface. We have to apply each layer of the composite material. That means, for example, here I've created one to model the transom, the transom part.

We can see we have one layer, one superior layer here, and a bottom layer here, and some lateral ones, like this one vertical that envelops our transom. But here we can see there are some yellow vectors. These vectors show us the reference direction of this oriented selection set.

That means that is the zero-degree angle for this part. We can have another direction different to this one to define the other parts of the same model. For example, here in some lateral, in some, let me see. Bottom. For example, it's the same. For example, for example, here.

In this part, in this yellow zone, the zero-degree direction is vertical. Following the geometry of our model of our boat at the end. That's the idea to work in ACP. We need to define all these reference directions in order to define the angle where we are going to orient our fibers then.

But this kind of vector of direction is defined in order to see how we are going to construct this structure. For example, we can define also, we must define also, the direction of the ply. That means in which direction are we going to stack every layer we add in the model.

For example, we can add the layers to the outside or in the inside of the of the of the boat. In this case, I define it in that way. In order to add all the place to the exterior. We do the same thing for each zone. For example, here we can see our reference vector. Is not horizontal.

Is defined following the edge of the blue line. The blue line. Of the blue geometry. We can see that here. And that's we and and that's the the way we really construct this this kind of of of parts. After that, the thing to do is to really define the layers, the stackups.

How are we going to do that? We are going to do it using the modeling groups. This modeling groups as where we really apply the layers. For example, here in the triangle. We defined a model imply for all the song for all this geometry for all these surfaces.

But at the end, we are applying a just one time. The model imply using the fabric. I define the stack up. I define this one. For example, here if I see the the properties. I define the stack up. I define the layer. The the properties here. I can see that I am using the stack up one.

And I used one number of layers. I can use for example three times four times any times the the seven layers of the stack up one. Or I can add. For example. A. One time the stack up one and then one one time or two times the individual fabric. I can define it as I wish.

Then we can see here we are defined that. And for example in the body. We have two two layers. That means I apply 14 layers in the zones. That's that's why I construct my my my composite in that way. We can see we have any of these. We have any of these here.

Once the the composite layup is constructed. We can see for example. I am going to hide that. And I am going to. To show. Let me orient the view like that. Okay. For example here we can see there are the green vectors. Who are the vectors indicating the orientation of this layer.

But if I pick the second one. I can see the. The yellow vector. Are oriented. The green vector. Is. Turned. In reference to the. To the yellow one. That means that it has I guess. 30 degrees. The third layer. 40 45. 0 degrees. Minus. 45 minus 30 and. Again 0. That's why we define our our place.

And in this way we can. Work with this. With this structure in that way we can do that. And we continue with which. With every every song we want. We can define. More layers. Men. Less layers in each song. And we construct our structure in a way. We want. Here for example.

I applied some reinforcement. We can see. We can see them here. For example. In this song. I applied. This one. In the. Taking the red and the yellow. Areas. We see here. For example. Here we have. Two times. Seven layers. We are using the fabric. The stack up. Two times. And. We have.

This kind of direction. I am. This one. For example. Is the. The main orientation. And. We can. We can. Use. The. The. The main orientation. If we see here. We have an angle of. Of 30 degrees. This is the. The angle between. The. The stack up. We created. A measure. With. The. The.

Oriented selection set. Defined. For example. Here. This song. Is. Geometrical. We have. Only. Here. This is. Zero degrees. But. My. Reinforcement. Is. My. Reinforcement. My. Fabric. Are. Oriented. And. 30 degrees. With. That. Okay. And. For example. Once. We have. Created. All. Of. Our. Structure.

We can. Visualize. Is. Very. Important. For. Example. We can. See. A. Composite. Structure. Here. We. Have. For. Example. We. Have. A. Base. Layer. Here. We. Have. Our. Reinforcement. We. Can. See. It. In. The. Middle. Then. We. Applied. Another. Layer. The. Composite. Materials. And. These. These.

A. Final. Layer. Has. Been. Applied. Only. In. This. Green. Zone. We. Have. We. Can. See. Here. The. Colors. Are. Corresponding. To. The. Thickness. Of. The. Surface. And. The. Level. And. The. Intersection. Of. The. Surface. We. Have. A. Layer. In. The. Center. And. The. Surface. We. Have. A.

Layer. In. The. Surface. And. The. Layer. Of. The. Layer. Of. The. Stack. Of. Material. And. That. Simply. Like. A. Filter. Where. We. Can. Define. Our. Composite. Structure. At. The. End. This. Is. The. Location. That. Means. That. If. We. See. That. In. In. Workbench. We. Have. A. Model. An. H. E.

P. Model. Where. We. Define. Our. Material. Our. Geometry. Then. A. Static. Or. Another. Structural. Model. It. May. Be. A. Model. Or. Harmonic. And. So. On. Any. Kind. Of. Analysis. Then. We. We. Are. Going. To. Define. The. Rest. Of. Modulation. For. Example. Here. We. Can. See. We. Have. Our.

Mesh. We. See. A. Superimposed. Mesh. That's. Why. That's. A. We. Can. See. That. Because. I. Am. Importing. Another. Solid. To. Steve. Our. All. This. Structure. But. If. I. If. I. Hide. It. Hide. Body. I. Have. Really. My. ACP. Mesh. We. Can. See. Here. All. The. Imported. Place. The. To. Look.

At. The. Plane. A. To. Have. More. Control. Of. Them. And. With. Here. We. Define. All. The. Rest. Simulation. Here. For. The. Demo. I. Just. Applied. Fixed. Support. Then. Is. The. Same. Thing. Like. Any. Another. Analysis. We. Define. We. Define. Our. Simulation. Our. I. Don't. Know. Our. Time.

Steps. And. So. Work. Then. We. Can. See. That's. Why. We. Have. Our. Maximum. Here. But. The. Most. Important. Thing. Is. The. Is. The. Composite. Special. Results. For. Example. We. Can. Define. A. Composite. Failure. Tool. Where. We. Can. See. That. Is. The. Interesting. Part. Because. We. Need.

To. Evaluate. We. Don't. Know. Which. Layer. Is. Going. To. Fail. We. Need. To. Know. That. And. Maybe. We. Can. Define. A. Composite. Results. For. Example. We. Can. Define. A. Composite. Failure. Failure. We. Need. To. Define. A. Composite. Failure. For. Example. We. Have. To. Define. A. Values.

We. Can. Use. It. Then. We. Have. Our. We. Have. Our. Response. I. Define. Some. Inverse. Reverse. Factor. That. Means. If. We. Have. A. Value. Greater. Than. One. That. Then. We. Can. See. Here. For. Example. By. Element. We. Can. See. The. Evaluation. Of. All. The. Criteria. We. Define. Here. For.

Example. I. Found. That. Some. Kind. Of. A. Any. Possibility. To. Be. Failed. For. Example. Here. And. So. One. For. Each. Element. We. Have. Just. One. Color. Because. All. Over. All. The. Element. We. Have. This. This. Label. We. Have. Here. For. Example. It. Says. E2T 22. That. Means. That. The.

Critical. Criteria. For. This. Element. Is. An. Strange. Failure. Criteria. Because. It's. E. 2. Because. It. Is. A. Big. In. This. Element. We. Have. Seen. That. Here. We. Can. See. For. Example. If. I. Return. Here. I. Can. See. There. Are. A. Lot. Of. In. This. Element. For. Example. Using.

This. Tool. We. Can. Create. A. Sampling. Point. Where. I. Can. Here. Here. I. Define. I. Select. Really. An. Element. And. We. Have. A. Stack. All. All. The. Place. We. Have. Seven. Four. Times. That. Means. Twenty. Eight. Layers. At. This. Point. All. Of. Them. Are. Created. From. The. Same.

Material. In. The. Zone. Okay. Then. The. Principal. Like. That. Okay. Then. We. Can. Evaluate. The. Failure. Modes. In. This. Zone. For. Example. We. Have. Seen. The. E. Two. T. Was. The. I. Don't. Know. What. The. A. Means. But. It's. Another. Criteria. Who. Is. The. Biggest. In. The. At. This.

Layer. But. Here. Is. The. E. Two. T. And. Its. Is. Not. A. Parting. To. The. To. The. Structure. In. This. Point. Maybe. We. Can. We. Can. Retire. From. The. Structure. Maybe. There. Is. Not. Any. Utility. The. E. One. The. E. Two. And. The. And. The. G. Model. In. The. Shield. Model. In. At. This.

Point. That. Is. That. Is. Mainly. Our. Our. Results. That. We. Have. A. Very. Good. Analysis. As. Any. Other. And. Okay. I. I. Guess. That's. All. For. My. Side. I. Would. Like. To. Know. If. There. Are. Some. Questions. Thank. You. For. Your. Interest. In. This. I. Have. A. Very. Much. Of.

Interest. In. Our. Life. And. Our. Life. And. Our. Life. And. Our. Life. Is. A. Very.
