This brief provides guidance for the application of cohesive models to determine damage and
fracture in materials and structural components. This can be done for configurations with or
without a pre-existing crack. Although the brief addresses structural behaviour the methods
described herein may also be applied to any deformation induced material damage and failure
e.g. those occurring during manufacturing processes. The methods described are applicable to
the behaviour of ductile metallic materials and structural components made thereof. Hints are
also given for applying the cohesive model to other materials.
