Abstract

The cohesive model can be used for any failure mechanism, i.e. it is applicable to any material and for any fracture mode, i.e. applicable to any loading. However, Mode II, Mode III and mixed mode fractures are of lower priority for engineering applications. In addition, no reliable procedure for parameter identification is available for any mode other than Mode I fracture as to the authors’ knowledge.
