Abstract: This paper presents the nonproportional cyclic elastoplastic behavior of structural steels under biaxial loading, through a combined experimental and analytical study. In particular, the work seeks to illustrate the cyclic ...

Abstract: This paper is concerned with the analytical modeling of the cyclic behavior of structural steels. The modified uniaxial two-surface model developed by Shen et al. in 1992 is generalized to a multiaxial two-surface model, ...
