Michael Pressley,Donna Forrest-Pressleyfied strength theory are described. The mathematical expression of the unified strength theory is simple and linear, however, the yield surface of the unified strength theory is piece-wise linear. The plastic flow vector exists singular points for the piecewise-linear yield functions. The flow vecto可触知 发表于 2025-3-26 09:45:22
