Finite Element Modelling of Delamination Onset in Polymeric Composite Material

Article Preview

Abstract:

Delamination is a well-known issue in polymeric composite materials. Interlaminar Shear Stress (ILSS) plays an important role in delamination initiation and thus its value needs to be monitored when designing a composite component. In this paper a Short Beam Shear experimental test of a carbon/epoxy specimen reproducing a Formula 1 component laminate is represented through a Finite Element analysis of two different models, one featuring 2D shell elements and the other 3D elements. ILSS results from both models are compared to experimental data in order to assess whether a 2D shell model can be used instead of its 3D counterpart, in favour of design versatility.
