Abstract The purpose of the paper is to present the study of elastic -plastic stress analysis in a spherical shell under the combined effect of pressure and temperature. The solution of the problem is obtained by using the concept of generalized strain measures and Seth's transition theory. It has been seen that circumferential stress has a maximum at the external surface of the spherical shell made of incompressible- as well as compressible materials. The thermal effect increases the values of stresses. Keywords: elastic-plastic, temperature, pressure, shell, stresses |
