• Stress-strain relations of commercialized metal in reloading in various directions after axial and torsional preloadings of various sequences and magnitudes are superimposed, are experimentally investigated. Experimental results are put in order on the basis of a double surface hardening model which consists of elastic, transitional hardening and steady hardening regions. Utility of the double surface theory for describing the complex plastic deformation behavior of metal is confirmed under combined stress conditions. It is also confirmed that the effect of the past deformation history on plastic properties of metal can not perfectly be liquidated in general by any following loadings. Effective stress-strain relation in the transitional hardening region, which is represented in non-dimensional expressions, can be shown by a specific expression without regard to material and prestrain history. Many other significant conclusions are obtained.
