Developed and implemented physics based crystal plasticity finite element models to describe the constitutive behavior of stainless steels and subsequently predict fatigue service life of weld deposited pressure vessel claddings. The tools were extended to identify regimes of applicability of component life prediction models to estimate and enhance the service longevity of weld claddings for different defects and service conditions. Effect of manufacturing methods on the service life of components was predicted. The constitutive models were extended to other classes of alloy systems.
Developed and implemented frequentist approaches to identify mixtures of extreme value distributions applicable to describing high cycle fatigue life. The method isolates the extreme values governing the tails of service life and provides an accurate assessment of the minimum service life for design procedures.

Multi-scale methods for imposing coarse-scale fields to fine-scale computational cells for continuous and discrete media were implemented relieving spurious, computational cell size dependent wavelengths in solution fields typical of commonly used boundary conditions. Fundamental length scales manifested by micromechanics of discrete media were identified. Network-cell and topological description of deformation mechanisms in discrete media were devised describing their anomalous dilatant behavior. The models developed are applicable for transport and manufacturing processes involving particulate media.
