Cohesive-Shear-Lag Modeling of Interfacial Stress .
Interfacial shear stress transfer of a monolayer graphene on top of a polymer substrate subjected to uniaxial tension was investigated by a cohesive zone model integrated with a shear-lag model. Strain distribution in the graphene flake was found to behave in three stages in general, bonded, damaged, and debonded, as a result of the interfacial stress transfer.

Numerical Simulations of Dynamic Fracture Growth .
The theory behind the cohesive zone model dates back to early work by Barenblatt and Dugdale (); they presented the basic concepts of the cohesive zone method. Tvergaard ( 1990 ) employed a quadratic traction–displacement jump model to analyze the failure by decohesion of the fiber-matrix interface.
