Abstract: Abstract An elastic domain with multiple yield surfaces brings about huge troubles to numerical computations due to singularities, while non-associative plasticity leads further to the open issue of whether constitutive integration is well posed. This… read more here.

Abstract: Abstract Recognizing the limitation of the existing yield surfaces for clays, a novel type of the yield surface is derived. The shape parameters allow for the distortion of the yield surface from an ellipse to… read more here.

Abstract: Abstract Subsequent yield surfaces of ductile solids, pre-strained in shear and/or tension, exhibit various characteristic features that depend on the proof strain used to detect yield. These features include kinematic hardening when the proof strain… read more here.
