Abstract
Plastic-deformation induced anisotropy and memorization of back stress due to preloading affect the current loading. These phenomena are exa mined with tension and/or torsion tests, using SUS 304. Considering bo th anisotropy, and movement and memorization of back stress, equi-plas tic surfaces are predicted. This explains the dependence of current lo ading on preloading well. Simulated strain paths during radial loading after shear straining show good agreement with experiments. (C) 1998 Elsevier Science Ltd. All rights reserved.
