Fracture tests for circumferentially through-wall STPG370 cracked pipes were simulated by elastic-plastic ordinary state based peridynamics where work hardening model was newly introduced. Three fracture tests were selected as objects of analysis with different crack angle and test temperature. Load-load point displacement curves were reproduced by the peridynamics while crack extensions were slightly slower than experimental results. Slant crack extension directions of specimens were also well reproduced by the peridynamics analyses.
