Peridynamic simulation of dynamic fracture in functionally graded materials subjected to impact load

Dynamic crack propagation assessment in functionally graded materials (FGMs) with micro-cracks is accomplished using bond-based Peridynamics (PD). The dynamic fracture behaviour of various FGMs’ material models studied Kalthoff–Winkler experiment. growth predictions and associated damage the specimen under loading conditions are considered. effect near macro-crack tips on toughening mechanism evaluated terms velocities. Stochastically pre-located modelled to obtain material. In addition, velocities time required for compared different FGM cases. It frankly found that if a propagates harder region specimen, decrease toughness increase contrast softer region. Furthermore, around decelerate enhance body depending gradation properties.
