Advanced fibre-reinforced plastic (FRP) composite materials are ideal for structural applications where high stiffness-to-weight and strength-to-weight ratios are required. Such materials are inherently heterogeneous. Typically, they are made of a polymeric matrix reinforced by continuous or discontinuous fibres.
The wide range of fibre and matrix types along with the multiple fibre arrangement possibilities makes FRP composites behave in a more complex way than conventional metals. As a result, they not only have a strong anisotropic behaviour but also predicting failure can be challenging.
In this webinar, we will explain how to predict intra-laminar failure in long continuous FRP composite structures subjected to real life multiaxial loading conditions. We will demonstrate how to select the right criterion for detecting critical regions where failure is likely to occur. We will also show how to accurately predict margin to failure.
