Composite Blade Analysis
Impact of Dependencies on Composite Blades
This video demonstrates the impact of various dependencies such as temperature, shear angle, and degradation factor on a composite blade. The material models are defined as functions of these three variables.
Simulation Overview
We will conduct a static analysis simulation to examine the variability and the first-ply failure of the model. The process begins with the shell model of the blade, which evolves into a solid-sick composite model created through extrusions. The model incorporates degradation factors and temperature effects.
Simulation Model Details
- Includes a field to account for temperature effects.
- Applies boundary conditions such as fixed support and velocity.
- Allows examination of various plies on the 3D model.
Results and Observations
Upon solving the model, we obtain results including deformations and stresses. Key findings include:
- First-ply failure is observed while activating draping.
- Increased criticity with added temperature.
- Further increased criticity with added degradation, highlighting potential failure spots.

This video shows the impact of various dependencies, such as temperature, shear angle, or degradation factor, on a composite blade, as shown in this model. The material models are defined as a function of those three variables: temperature, shear angle, and degradation factor.
We will use a subsequent simulation for a static analysis, where we will look at the variability and the first-ply failure of the model. The process starts with the shell model of the blade.
Ultimately, when we create the composite model, it will be a solid-shell composite model that we created through extrusions, and we include the degradation factors in the model. We will include temperature effects. We add a field to the simulation model, as shown here with the full model.
We have some boundary conditions, such as fixed support and velocity. We can look at the various plies of the models on the 3D model, as shown here on one ply. We can look at another one here.
When we solve the model, we will get deformations and stresses, as well as different results, such as those shown here. The basic data shows some first-ply failure while activating draping. It also shows a different region.
Criticality is increased when we add temperature, and when we add degradation, the criticalities are even worse, showing different spots where we need to look for potential failure of our blade.
