Flat hourglass specimens are proposed to assess the compressive behaviour of FRP utilizing two testing techniques. The hourglass shape helped to ensure failure at the centre of the specimen and to minimize in-plane stress concentration in this zone.

Modelling the damage of composite materials is not an easy task because different modes of ruins coexist: Fiber matrix decohesion ,matrix cracks, delamination , and fiber cracks. In the case of laminated composites, the matrix cracks have the particu
