Abstract: A new method to calculate the limit load of thick wall cylinder under high pressure based on Yu's unified strength theory and unified slip line field theory, and a unified solutions are obtained. Solutions based on Tresca, Mises, Mohr-Coulomb and twin shear strength theories is special cases of the unified solutions. The corresponding solutions of different materials can be got from it. The unified solution can not only be used to fit the properties of the materials with different tension-pressure strength but also the ones with equal tension-pressure strength. The result is of much importance in engineering and economy.
Key words: Thick wall cylinder, Ultimate loads, Yu's unified strength theory
