Numerical Simulation of Sample Scale Intense Shear Bands in Uniaxial Tension Test of Aluminum Alloys

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.Copyright © 2005 by ASME
