Modeling the Behavior of Impact Induced Multiple Delaminations under Compressive Load

A two-part study is presented focusing on post-impact behavior prediction of compression after impact (CAI) specimens. The first part is dedicated to the study of cohesive zone model (CZM) and mesh density parameters as well as to the evaluation of their influence on resulting simulation accuracy and computational costs. For that purpose, two different tests are replicated by numerical simulations: double cantilever beam (DCB) and end-notched...
