| Abstract: | The stress paths in the transient thermoelastoplastic analysis are strongly dependent upon the history of temperature, whereas stresses in the thermoelastic analysis are determined uniquely by the distribution of temperature. This paper treats the effect of the history of temperature on the thermoelastoplastic solution of a thick-walled tube. The transient state of stresses in the tube when subjected to inner-surface heating in which the temperature has an exponential time history is discussed in detail, on the assumption that thermal and material properties depend on temperature. |
