Composite sandwich structure with a notch in bending/torsion: test and simulation up to rupture

Résumé

It is proposed a new test on a large sandwich notched specimen loaded in static bending/torsion and consisting of woven fabric GFRP laminates and foam material. The aim of this test is to generate crack initiation and propagation around the notch. This test is used to validate a model based on continuum damage mechanics and a nonlocal criterion developed since several years. Numerical results compared to DIC and the force at failure show the efficiency of the proposed approach.
