Formulations of strain gradient plasticity

Abstract : In the literature, different proposals for a strain gradient plasticity theory exist. So there is still a debate on the formulation of strain gradient plasticity models used for predicting size effects in the plastic deformation of materials. Three such formulations from the literature are discussed in this work. The pros and the cons are pointed out at the light of the original solution of a boundary value problem that considers the shear deformation of a periodic laminate microstructure.
