Abstract: Abstract This work presents an extension of Oxley's shear zone theory by substituting the original velocity-modified power form by the widely used constitutive material model developed by Zerilli and Armstrong (ZA). Used are variations of… read more here.

Abstract: Density functional calculations for metallic lithium along a cuboidal bcc-to-fcc transformation path demonstrate that the bcc phase is quasi-degenerate with the fcc phase with a very small activiation barrier of 0.1 kJ mol-1, but becomes… read more here.
