Numerical investigation of crack growth behaviour using a cohesive zone model
This thesis concerns modeling ductile fracture using a cohesive zone model (CZM) and finite element (FE) methods. A FE program system (FECGS), which includes a pre-processor and a post-processor, has been developed for that purpose. A simple CZM has been

A simple cohesive zone model that generates a mode-mixity dependent toughness
A simple, mode-mixity dependent toughness cohesive zone model (MDGc CZM) is described. This phenomenological cohesive zone model has two elements. Mode I energy dissipation is defined by a traction–separation relationship that depends only on normal ...
