Equivalent plastic strain gradient crystal plasticity – Enhanced power law subroutine

GAMM-Mitteilungen, 2013
AbstractA gradient crystal plasticity theory is presented including a defect energy based on the gradient of an equivalent plastic strain measure. Preserving the single crystal slip kinematics, the gradient hardening contribution models dislocation long range interactions adding a back‐stress term to the flow rule, similar to other gradient crystal ...

A strain gradient theory of plasticity

International Journal of Solids and Structures, 1970
Abstract A theory which includes first and second strain gradients is proposed as a model for plastic deformations. Heuristic arguments for including the gradients are also given. The main goal is to develop a logical framework in which behavior on a small scale can interact with the response on a larger one.

A study of growth and remodeling in isotropic tissues, based on the Anand‐Aslan‐Chester theory of strain‐gradient plasticity

GAMM-Mitteilungen, 2019
Motivated by the increasing interest of the biomechanical community towards the employment of strain‐gradient theories for solving biological problems, we study the growth and remodeling of a biological tissue on the basis of a strain‐gradient ...

A Dissipative System Arising in Strain-gradient Plasticity

Applied and Industrial Mathematics in Italy III, 2009
We discuss a nonlocal and fully nonlinear system of partial differential equations which arises in a strain-gradient theory of plasticity proposed by Gurtin (J. Mech. Phys. Solids, 2004). The problem couples an elliptic equation to a parabolic system which exhibits two types of degeneracies: the first one is caused by the nonlinear structure, the ...
