On bounded rate constitutive model: Application to objective failure prediction

The most widespread approach to overcome the lack of consistency of material models with respect to failure is the non-local approach. Here we propose to discuss an alternative approach - the bounded rate constitutive model, with its advantages and disadvantages. Several examples will illustrate the main properties of bounded rate-dependent models and their identification: ductile failure of a metallic material, dynamic delamination - failure and erosion of laminates submitted to high velocity impact.
