Comparison between cohesive zone models
Communications in Numerical Methods in Engineering, 2004AbstractCohesive zone models (CZMs) are widely used for numerical simulation of the fracture process. Cohesive zones are surfaces of discontinuities where displacements jump. A specific constitutive law relating the displacement jumps and proper tractions defines the cohesive zone model.

A New Cohesive Zone Model for Mixed-Mode Decohesion
2006This paper focuses on the frequently adopted exponential cohesive zone law of Xu and Needleman (Xu and Needleman [1]). In spite of its wide applicability, this cohesive zone law gives an unrealistic physical response under most mixed-mode loading conditions.

Cohesive-Zone Modeling of Adhesive Joints
2013Two distinct failure criteria have traditionally been used to model adhesive joints: a strength-based criterion using the cohesive strength of the adhesive, and an energy-based criterion using the toughness of the adhesive. In practice there are conditions under which the properties of a joint may be controlled by either one of these criteria, or by ...

Thermal de-cohesion model for time of craze failure in cohesive zone
Theoretical and Applied Fracture Mechanics, 2004Abstract The cohesive parameter corresponding to craze failure time is predicted for thermoplastics material. A craze failure separation criterion is proposed for a cohesive zone subjected to a melt layer formed and thickened by adiabatic deformation heat from a craze drawing.
