abstract

  • The present work focuses on the study of the development of shear localization through the use of the conventional finite element method which does not involve the non-associative flow rule, yield surface vertex or void growth model. The various aspects, i.e. geometry idealization, element type, solution procedure, convergence, and particularly the representation of true-stress and plastic strain relationship, are emphasized. The predicted profile of the deformed specimen, shear band angle and strain distribution show an excellent agreement with experimental observations.
