In this paper, a trilinear cohesive zone modeling approach available in the explicit nonlinear finite element software LS-DYNA is used to model the dynamic impact failure of an adhesive layer. This approach is an improvement over simpler cohesive zone models presented in the literature. The model...

In the first part of this thesis, a validated polyurethane adhesive model is implemented into a system-scale ceramic/armor model for ballistic impact simulations. Here, the trilinear cohesive zone (TCZM) technique is used to simulate the dynamic failure of SikaForceTM6 7752-L60 polyurethane...

As an advanced fracture model, the Generalized Incremental Stress State dependent damage MOdel (GISSMO) provides non-linear damage accumulation formulation to better predict ductile fracture initiation associated with a wider range of material stress states. In this study, we simulate the...
