Abstract: Abstract We establish an atomistically-informed model for predicting the non-Schmid behavior of critical stresses for bcc to orthorhombic (L21 to 18R) martensitic transformation in CuZnAl alloys. The interplay between the stacking fault displacements and the… read more here.

Abstract: Abstract The extent that non-Schmid stresses influence the mobility of dislocations in Al is studied using molecular dynamics (MD) simulations. Specifically, mobility laws for straight screw, 30°, 60° and edge dislocations are atomistically derived for… read more here.

DOI: 10.1016/j.ijsolstr.2017.01.003
Abstract: Abstract Understanding and modeling the plastic deformation of body-centered cubic (BCC) metals involves considering non-Schmid (NS) driving forces to move dislocations. Here, the deformation of individual single crystals results not only from the resolved shear… read more here.
