Adrian van Olphenfied 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

Hans-Joachim Radüov (1971), Martin (1973), Yan (1988) and Panoyotomakos (1999). A new characteristics method for plane stress problems was established based on the twin-shear yield criterion by Yan and Bu in 1993 and 1996. The three different characteristic methods based respectively on the twin-shear yield criterio

Frank Waldfahrerd strength theory is used to obtain the unified solutions of plastic limit and shakedown analysis of pressure vessel. These results can be suitable for a wide range of materials and engineering..In these solutions, the SD effects (effect of compressive-tensile strength difference) and effect of inte
