The size of the cohesive zone at a crack tip
Engineering Fracture Mechanics, 1975Abstract Although it is markedly dependent on both the stress at the cohesive zone tip and the displacement at the crack tip, the cohesive zone size at the critical stage of crack extension is shown to be relatively insensitive to the detailed form of the force law describing the non-linearity of material behaviour.

Time Dependent Fracture and Cohesive Zones
Journal of Engineering Materials and Technology, 1993This presentation is concerned with the fracture response of materials which develop cohesive or bridging zones at crack tips. Of special interest are concerns regarding crack stability as a function of the law which governs the interrelation between the displacement(s) or strain across these zones and the corresponding holding tractions.

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.

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 ...

Numerical aspects of cohesive-zone models
Engineering Fracture Mechanics, 2003Abstract The importance of the cohesive-zone approach to analyse localisation and failure in engineering materials is emphasised and various ways to incorporate the cohesive-zone methodology in computational methods are discussed. Numerical representations of cohesive-zone models suffer from a certain mesh bias.
