ABOUT SHOAYB ZIAEI

Ph.D. research supported development of fundamental understanding of fracture, plasticity, and high temperature behavior of metallic alloys with special focus on zirconium alloys used as cladding in nuclear reactors, and high temperature application.• Developed large scale, specialized finite element (FE) codes in a dislocation density based crystal plasticityframework and implemented new material models into non-linear FE analysis of large plastic deformations andcrack nucleation and growth in hexagonal close packed (hcp) crystalline materials.• Investigated high temperature plasticity and fracture behavior of zircaloy by using a coupled thermo-mechanicalFE model.• Developed physics-based and FE models to investigate hydrogen embrittlement and hydride assisted failuremodes in crystalline materials, by investigating dislocation density evolution at the interface of hcp grains andfaced centered cubic (fcc) hydrides, and analyzing its effects on the strength and toughness of the material.• Modeled twin-grain assisted fracture nucleation and propagation in crystalline materials.Postdoctoral research focused on modeling and control of thermo mechanical failure modes in thin film multilayered systems.• Investigated models for channel cracking, interfacial delamination, and effect of adhesion strength of indium tin oxide (ITO) and indium zinc oxide thin films on polyethylene terephthalate (PET) and glass substrate under tensile loading.• Investigated the effect of different loading conditions on multilayer thin films on PET substrate.• Modeled the effect of gold, and silver layers on ITO/IZO thin films.
