The cohesive surfaces are placed in the plane of the expected crack propagation, as shown in Figure 3. When the critical displacement 𝛿0 is reached (according to the TSL), traction drops to 0, and local separation occurs, increasing the crack length. Figure 3.

Abstract. This paper reviews the cohesive process zone model, a general model which can deal with the nonlinear zone ahead of the crack tip––due to plasticity or microcracking––present in many materials. Furthermore, the cohesive zone model is able to adequately predict the behaviour of uncracked structures, including those with blunt ...
