THE ANALYSIS OF LIMIT INNER PRESSURE OF THICK WALLED TUBE AND SPHERE SHELL WITH DIFFERENT STRENGTH IN TENSION AND COMPRESSION BY THEORY OF GENERALIZED TWIN SHEAR STRESS STRENGTH

In this paper elastoplastic stress analyses for thick-walled tube and sphere shell with different strength in tension and compression are conducted using the theory of generalized twin shear stress strength.They include elastic limiting inner pressure,plastic limiting inner pressure,elastoplastic stress,and the relation between inner pressure and elastoplastic zoned radius of thick-walled tube and sphere shell.These results are dependent on tension-compression ratio of the material.The calculated limiting i...
