Composite materials are widely used in the Aerospace and Defense industry for their high strength-to-weight ratio, durability, and resistance to fatigue and corrosion. However, the design and analysis of composite structures can be challenging due to their anisotropic and heterogeneous nature.
Finite element analysis (FEA) help our engineers to optimize the design of composite structures for weight and performance, and to accurately predict the impact damage, including fiber and matrix failure, delamination, rupture, and crack propagation.
One of the key advantages of FEA simulations in composite design is the ability to determine optimal ply lay-up structures. By simulating the mechanical behavior of composite materials with different ply orientations, our engineers can identify the most efficient and effective ply lay-up structures for a given application. This can lead to significant weight savings and improved performance of the composite structure.
Another important application of FEA simulations in composite design is the prediction of impact damage. Composite structures are vulnerable to impact damage from sources such as hail, bird strikes, and debris. FEA simulations can predict the extent and severity of damage, including fiber and matrix failure, delamination, rupture, and crack propagation. This can help to improve the durability and reliability of composite structures and ensure their safe operation.
