Abstract : The work performed in the reporting period has been focused on completion of Task 1.2, and a part of Task 1.3 and Task 2.2, 2.4 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 activities related to Task 2 cover the new peridynamic model for multi-phase composites which can introduce the presence of pores and manufacturing defects in the intermediately-homogenized model of fiber-reinforced composites.
