Abstract
A noval particle-based method is proposed for the static and dynamic fracture simulation of solids. The proposed particle method includes multi-body potential to conserve the volumetric deformation under general loading conditions. First, the formulation of the proposed particle method and the derivation of model parameters are given. The numerical algorithm for the dynamic system solution is discussed. Following this, a quasi-static fracture simulation for a composite plate with multiple holes is performed and compared with existing experimental observations. Next, the proposed method is applied to model a dynamic fracture with high speed impact problem and the simulated failure pattern is investigated with different impacting velocities. Finally, some conclusions are drawn based on the proposed study.
