Piecewise-linear generalizable cohesive element approach for simulating mixed-mode delamination

A cohesive element formulation is proposed that provides a general framework to approximate experimentally measured Traction–Separation Law (TSL) shapes. Unlike other approaches, it does not assume specific TSL shapes, such as bi-linear or exponential. The TSL shapes are defined generally, in a piec...
