Modelling of Compressive Transverse Cracking on Composite Laminates

About the Project

In analyses of failure in composite laminates, extended finite element analyses using Abaqus (or Ansys) might prove convenient for the prediction of transversal cracks on composite laminates subjected to compression.

Cracks are represented as a strong discontinuity in the displacement field. Under compression cracks tend to be inclined within the layer mid-plane which can lead to failure where the outer plies are pushed out of the plane of the laminate and eventually buckle.

In principle, it is possible to model the inclined crack plane with the Finite Element Method. The basic idea is that the direction into which stiffness recovery under compression takes place is altered for a crack that develops under compression. Only one layer of elements per ply might be used, which is typically done for reasons of computational efficiency.

The project can also include simulations where in-plane shear is acting on the potential crack plane.
