Cyclic deformation of metallic materials depends on the interaction multiple mechanisms across different length scales. Solid solution atoms, vacancies, grain boundaries, and forest dislocations interfere with dislocation glide increase macroscopic strength. In single phase under cyclic loading, localization densities in sessile substructures explains a significant fraction strain hardening. Up...

A crystal plasticity-based constitutive model is developed to describe the thermomechanical behavior of pseudoelastic NiTi single crystal. The includes, for first time in literature, all inelastic mechanisms influencing fatigue SMAs a finite strain framework: martensite transformation, deformation slip austenite at high-temperature, twinning large strain, transformation-induced plasticity (TRIP...

Hybrid fiber-reinforced polymer composites comprised of glass and steel fibers in a resin matrix have been shown to increased strength energy dissipation compared conventional composites. However, methods for simulating the mechanical behavior combinations hybrid yet be advanced. In this study, non-hybrid with off-axis were manufactured extracted coupons subjected half-cyclic tensile testing. T...
