This paper provides ductile tearing simulation for Battelle full-scale pipe tests with proposed damage method based on the multi-axial fracture strain model and stress reduction technique. Materials included in this research are one carbon steel and one stainless steel. Tensile and compact tension (C(T)) specimens are simulated, and then, simulation results are compared with test results to determine the failure criteria. Pipes containing through-wall crack and surface crack are simulated by proposed damage method and the results are compared with test data for verification of proposed method. It is shown that predicted simulation results and experimentally measured values are showing overall good agreements. Crack initiation and maximum loads are predicted to characterize the fracture behaviour of full-scale pipes.
