    • ...Experimental findings (see, for example, Mair and Pugh [1], Phillips and Tang [3], Phillips et al. [4] and Wu and Yeh [10]) show that the subsequent yield surface can expand in size, translate, distort, and rotate depending on the material being tested and also on the loading path in the stress space...
    • ...To this end, we establish a procedure that utilizes the experimentally obtained yield surfaces of Wu and Yeh [10] to determine the material parameters of the theory of Wu et al. [11]...

    • ...Wu and Yeh [10] argued from the viewpoint of loading surface that the surface should include the prestress point, since in a continuous loading/unloading, the load is always at the prestress point...
    • ...Thus, the surfaces presented by Wu and Yeh [10] are loading surfaces...
    • ...Also, experimental results of Wu and Yeh [10] show that there is no isotropic hardening for 304 stainless steel, i.e., f(z) = 1 and dz = d~. 22 H.C...
    • ...Although the results of that calculation were satisfactory compared to the set of experimental data reported in Wu et al. [8], there was a major disagreement known only after the experimental results of Wu and Yeh [10] were available...
