Mixed-Mode Delamination of a Composite Laminate

Application ID: 76331

Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the implementation of a CZM with a bilinear traction-separation law in a laminated composite using the Layered Shell interface. The capabilities of the CZM to predict mixed-mode softening and delamination propagation are demonstrated in the model.

This example is an extension of the Mixed-Mode Debonding of a Laminated Composite model in which the Layered Shell interface is used to model delamination. The results are compared with the model created using the Solid Mechanics interface.
