Abstract
The stress-strain relations of metals in loading along straight stress paths (or straight strain paths) with a bend are investigated experimentally as well as theoretically in the deviatoric stress (or strain) space. Equations of the equi-plastic strain surfaces of various metals after preloadings are given on the basis of the experimental results obtained by subjecting this-walled tubular specimens to combined axial load and torsion. Stress-strain relations for various loading paths are calculated using the equi-plastic strain functions. There is a good agreement between the calculation and the experiment.Keywords
