Composite Materials Simulation and Failure Analysis

The light, strong and versatile properties of composite materials make them attractive for many types of manufacturing. Composite materials like carbon fiber (CFRP), typically used in the aerospace and automotive sectors, are being used increasingly in energy, sports, construction and marine applications. Their composite nature, however, makes accurate simulation a challenge.

Ansys offers a complete suite of tools to help you overcome this challenge. Front and center is Ansys Composite PrepPost (ACP), a dedicated tool for composite layup modeling and failure analysis. You can generate layered composite models for implicit and explicit structural and thermal, as well as fluids, simulations. ACP provides efficient layup and best-in-class solid element modeling capabilities and a platform that offers many ways to exchange model information. It supports the vendor-independent HDF5 composite CAE file format for communication with third-party tools. Beyond the modeling of composite structures, Ansys Composite Cure Simulation (ACCS) simulates the curing manufacturing process. It helps you to simulate the curing process of a part and predicts residual stresses and process- induced distortions.

Efficient Engineering of Layered Composite structures

Composite materials are formed from the combination of two or more layered materials, each having very different properties. Composite materials have become a standard for manufacturing products that are both light and strong.  Additionally, composites provide enough flexibility so that products with complex shapes, such as boat hulls or surfboards, can be manufactured.

Modeling the Composite Stackings and Orientations

Ansys Composite PrepPost software provides all the necessary functionality for the analysis of layered composite structures. An intuitive interface efficiently defines materials, plies and stacking sequences. Materials can be accurately oriented on the structures using very flexible tools based on coordinate systems definitions.

Understanding the Product’s Performance

Ansys Composite PrepPost software offers a wide choice of state-of-the-art failure criteria, along with post-processing capabilities to allow an in-depth investigation of product behavior. The results for the structure can be looked at globally, or viewed in detail down to the layer level, which enables users to identify accurately reasons a structure could potentially fail. Design iterations can easily be performed to take into account geometric changes or material variations.

Toward Manufacturing

Useful for the analysis of an end product, the draping capabilities of Ansys Composite PrepPost software allow users to correctly identify the exact orientation of every layer of the composite. A flat-wrap capability and the ability to create ply books help in product manufacturing.
