Guidelines for Applying Cohesive Models to the Damage Behaviour of Engineering Materials and Structures
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
