Elastoplastic Stress and Strain Distribution in a Finite Plate With a Circular Hole Subjected to Unidimensional Load

Abstract

This paper deals with the experimental determination of the elastoplastic stress and strain distribution around an empty circular hole in a finite aluminum plate subjected to a unidimensional load as the deformation increases from the elastic far into the plastic field. The strains were measured using the moire method. The stresses were computed by means of the Prandtl-Reuss stress-strain relationships presented in a convenient form for the case of a strain-hardening material.
