Abstract: A strain‐space‐based plasticity model is proposed to represent the softening as well as hardening behavior of concrete under low confining pressure. Unlike the stress‐space plasticity theory based on the Drucker's postulate, ...

Abstract: The dynamic response and critical state of an inelastic simply supported column under an axial impact are studied. This problem is analyzed by solving the dynamic Bernoulli‐Euler equation with an axial inertia effect within ...

Abstract: This paper deals with the elastoplastic large deflection analysis of thin steel plates subjected to in-plane cyclic compression and tension using the finite element method. The modified two-surface plasticity model, recently ...

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, ...
