On bounded rate constitutive model: Application to objective failure prediction

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