Abstract


The present study presented a numerical model for the tensile damage in fiberreinforced composites with an open hole, using a peridynamics theory. Especially, peridynamics theory can deal with the damage in the composites having arbitrary fiber orientations by setting the bond properties (bond constant and critical stretch) appropriately. We compared two approaches for the peridynamics analysis of fiberreinforced composite materials, proposed by Oterkus and Madenci [1] and Ghajari et al. [2] and discussed the advantages and disadvantages of the peridynamics modeling for the damage in composites with curvilinear fiber paths. Finally, we reproduced the multiple-type and multiple-site damage in multi-ply laminated composites with arbitrary fiber orientations, using peridynamics simulations.
