Crack Propagation Analysis of Cracked Pipes Subjected to Cyclic Load by Peridynamics

Abstract

Recently, peridynamics (PD), which is a type of particle methods and can naturally describe material failure, is applied to several applications. In this work, ductile fractures of large cracked pipes subjected to cyclic load are simulated by work hardening type elastic plastic ordinary state-based PD. As a result, the number of load cycles and crack propagation behaviors were reproduced by the simulations.
