DOI: 10.1016/j.commatsci.2018.02.035
Abstract: Abstract In previous work, bond-order potentials (BOPs) have been used to establish a general yield criterion, different from the Schmid law, for the glide of 〈1 1 1〉/2 screw dislocations on {1 1 0} planes in body-centered cubic metals,… read more here.

DOI: 10.1016/j.ijsolstr.2017.04.006
Abstract: Abstract In this paper a three-dimensional analytical criterion for description of the onset of plastic deformation in cubic single crystals is presented. The criterion is pressure-insensitive and form-invariant to any transformation belonging to the symmetries… read more here.

DOI: 10.1016/j.mechrescom.2021.103693
Abstract: Abstract It is generally believed that the choice of the yield criterion used to describe the plastic behaviour of isotropic metallic materials does not affect much the accuracy of the predictions of forming operations. For… read more here.
