On the strength-ductility modifications in pure copper after severe plastic deformation
The aim of this work is to investigate experimentally and numerically the modifications of both strength and ductility after processing by severe plastic deformation, using several passes of repetitive corrugation and straightening on sheets made of pure copper. Experimental stress–strain curves are determined before and after processing in order t...
The formability of twinning-Induced plasticity steels predicted on the base of Marciniak-Kuczynski theory
The purpose of this work is to predict and analyze the formability of twinning - induced plasticity steels through the Marciniak-Kuczynski (MK) theory with emphasis on the solutions for improving the prediction results. The selected constitutive equations involve the Yld00-2d of Barlat et al. (2003) plane stress yield function, the Swift strain-har...
