Abstract
The conceptual simplicity and the ability of cohesive finite element models to describe
complex fracture phenomena makes them often the approach of choice to study dynamic
fracture. These models have proven to reproduce some experimental features, but to this
point, no systematic study has validated their predictive ability; the difficulty in producing
a sufficiently complete experimental record, and the intensive computational requirements
