Abstract:

The work peifarmed in the reporting period has been focused on completion of Tasks 1.2 on ply lavel cracking and 1.3 related to Synergistic Damage Mechanics and Tasks 2.2 and 2.4 related to Peridynamics, as described in the project proposal. The activities related to Task 1.2 concern growth and instability of initiated cracks in the environment of the disordered fiber distribution, and Task 1.3 evaluates the effect of these cracks on the response of the composite to imposed impulses. The specific focus in the reporting period was to study the effect of voids on crack initiation. The activities related to Task 2 cover the new peridynamic model for elasticity and fracture at an interface in a multi-phase composites.
