Application of the Discontinuous Solid-Like Shell Element to Delamination

A possible failure mechanism in layered composite materials is delamination. This mechanism can be analysed numerically using the discontinuous solid-like shell element. In this element, the delamination crack can occur at arbitrary locations and is incorporated as a jump in the displacement field by using the partition-of-unity property of finite element shape functions. The performance of the element is demonstrated by a small example.
