Abstract: The influence on macroscopic work hardening of small, spherical, elastic particles dispersed within a matrix is studied using an isotropic strain gradient plasticity framework. An analytical solution, based on a recently developed yield strength model… read more here.

Abstract: Abstract A thermodynamically consistent theory of strain-gradient plasticity in isotropic solids with mobile incoherent interfaces is developed. The gradients of plastic strain are introduced in the yield functions, both of the bulk and the interface,… read more here.

DOI: 10.1016/j.jmps.2018.09.011
Abstract: Abstract A fairly general formulation for rate-independent strain-gradient plasticity is studied. It includes the possibility of both “energetic” and “dissipative” higher-order stresses and a general effective plastic strain-rate E ˙ , which is convex and… read more here.
