Abstract

As a companion paper of Part I, this paper presents ductile tearing simulation results of STS410 through-wall cracked pipe test data with different amplitudes of load-controlled fully-reversed cyclic loading. The multiaxial fracture strain energy damage model is used with the Chaboche model. The simulated crack growths are not dependent on the ratcheting term in the Chaboche model, but deformations are slightly sensitive. Simulation results suggest that acceleration and retardation behavior in crack growth rates due to the load sequence may not occur under large-amplitude cyclic loading.
