Simulation of fracture and fatigue damage in stainless steel 304 using a cohesive zone model
In the present paper a cohesive zone model coupled with monotonic and cyclic damage mechanisms for simulating elastic-plastic fracture and fatigue crack growth is introduced and applied for investigating failure processes in compact tension specimens.Fracture and fatigue crack tests are conducted on the compact tension C(T) specimen made of stainless steel 304 to study crack growth behavior under fracture and low cycle fatigue loading condition associated with severe elastic-plastic deformations.A good agreement between the prediction and the experimental result is obtained from the present simulations.It confirms that the suggested cohesive model in conjugation with the nonlinear damage evolution equations is applicable for describing the material degradation behavior of stainless steel 304 under both monotonic and cyclic loading with large plastic deformations.
