Traditional macro-scaled plasticity theories may not be fully valid and accurate in study of
meso-/micro-scaled deformation due to the existence of size effects (SEs). In …

Traditional metal forming theories are not accurate in the analysis of micro/meso scale metal
deformation behavior due to the so-called size effect. As the deformation process scales …
