Abstract: Abstract In this work, we investigate the relationship between an intense slip band (ISB) and the zone of large lattice rotations that forms ahead of the tip of the ISB. We develop a crystal plasticity… read more here.

Abstract: Abstract Two-dimensional discrete dislocation plasticity (DDP) calculations that simulate single crystal films bonded to a rigid substrate under sliding by a rigid sinusoid-shaped asperity are performed with various contact sizes. The contact between the thin… read more here.

DOI: 10.1016/j.ijrmhm.2021.105734
Abstract: The plastic deformation mechanisms of tungsten carbide at room and elevated temperatures influence the wear and fracture properties of WC-Co hardmetal composite materials. Although the active slip planes and residual defect populations of roomtemperature deformed… read more here.
