...Rajesh Prasannavenkatesan; David L. McDowell Using a three-dimensional crystal plasticity model for cyclic deformation of lath martensitic steel, a simplified scheme is adopted to simulate the effects of shot peening on inducing initial compressive residual stresses. The model is utilized...

... martensitic steels. The formulation is based on accounting for variant morphologies and orientations, retained austenite, and initial dislocations densities that are uniquely inherent to martensitic microstructures. The effects of variant distributions and arrangements are investigated for different crack...

The as-received sample was characterized first at a frequency of 0.1 Hz per loop after demagnetization at 1 Hz. The same parameters were used to characterize...
