Thermoelastic finite element analysis of subsurface cracking due to sliding surface traction
Article Abstract:
A linear elastic fracture mechanics analysis of subsurface crack propagation in a half-space subjected to moving thermomechanical surface traction was conducted utilizing the finite element method. The crack propagation properties were interpreted in view of results for the directions and magnitudes of the maximum shear and tensile stress intensity factor ranges, respectively. It was found that while frictional heating showed a negligible effect on the crack propagation direction, it increased the in-plane crack growth rate and reduced the critical crack length at the start of out-of-plane crack growth at the right tip due to the tensile mechanism.

An approach for fatigue life prediction
Article Abstract:
A robust approach is developed to predict the fatigue life from crack initiation to final failure. The approach developed is based on the cyclic plasticity of materials and both crack initiation and crack growth can be modeled simultaneously with a set of cyclic plasticity material constants and a set of fatigue materials constants.
