摘 要：Limit analysis problem, coupled with finite element method and mathematical programming method, is a direct method to predict the load bearing capacity of solids and structures. Many work have been devoted to isotropic structures based on von Mises yield criterion. This paper turns to consider the orthotropic structures. Based on Hill s yield criterion [1], a numerical method is presented for the static limit analysis of 3-D orthotropic structures, where the temperature parameter method is used to construct the self-equilibrium stresses.
