Abstract In the research, the dynamic fracture failure problem of functionally graded
materials (FGMs) containing two pre-cracks was analyzed using a bond-based
Peridynamic (PD) method numerical model. The two convergence of decreasing the area
of PD horizon (δ-convergence) and uniform mesh refinement (m-convergence) were
studied. The effects of both crack position and distance between two cracks on crack
propagation pattern in FGMs plate under tensile loads are studied. Furthermore, the effects
of different gradient patterns on the dynamic propagation of cracks in FGMs are also
investigated. The simulate results suggest that the cracks positions and the distance
between them can significantly… More >
