### ELASTIC-PLASTIC TRANSITION STRESSES IN A TRANSVERSELY ISOTROPIC THICK-WALLED CYLINDER SUBJECTED TO INTERNAL PRESSURE AND STEADY-STATE TEMPERATURE

**ABSTRACT**

Elastic-plastic transitional stresses in a transversely isotropic thick-walled cylinder subjected to internal pressure and steady-state temperature have been derived by using Seth's transition theory. The combined effects of pressure and temperature has been presented graphically and discussed. It has been observed that at room temperature, thick-walled cylinder made of isotropic material yields at a high pressure at the internal surface as compared to cylinder made of transversely isotropic material. With the introduction of thermal effects isotropic/transversely isotropic cylinder yields at a lower pressure whereas cylinder made of isotropic material requires less percentage increase in pressure to become fully-plastic from its initial yielding as compared to cylinder made of transversely isotropic material.
