ON DEFORMATION STABILITY AND DUCTILE DAMAGE IN NANOTWINNED METALS
… of this thesis is to understand the role of twin boundaries (TBs) in the deformation and failure characteristics of nanotwinned (NT) materials. To that end, we implement a crystal plasticity finite element framework for nanotwinned FCC metals, which accounts for slip gradients that are …

Investigating the Effect of Austenite Grain Size and Grain Boundary Character on Deformation Twinning Behavior in A High-Manganese TWIP Steel: A TEM In-Situ Deformation Study
… (UFG) high manganese austenitic twinning-induced plasticity (TWIP) steels have been found to overcome the strength-ductility trade-off but their underlying mechanism of discontinuous yielding behavior has not been well understood. In this study, our systematic TEM characterization …
