• This study replaces the material parameter in the scaling function of the intrinsic time scale, as proposed by Pan et al.^<(1)> with an exponential function. Thus, the endochronic theory can be used to simulate the creep behavior of material under multiaxial loading. Experimental creep-test data obtained by Ohashi et al.^<(2)> on type 304 stainless steel at 650℃ under nonproportional repeated loading are used for evaluating the theoretical simulation. In addition, a simple endochronic creep model proposed by Lee^<(3)> and four creep models employed by Kawai^<(4)> are also included herein. It is shown that the experimental results are aptly described by the novel theoretical approach demonstrated from a comparison with the theoretical prediction from models employed by Lee^<(3)> and Kawai^<(4)>.
