摘要:
Based on Tresca's yield condition and its associated flow rule, the elastic-plastic deformation of a heat-generating tube with free ends is investigated by taking into consideration the influence of the temperature dependence of the yield stress. It is found that the expansion of the inner plastic zones as well as the stress state are affected markedly owing to the reduction in the yield stress at elevated temperatures. The stress distribution and the expansion of different plastic regions are displayed graphically and discussed.
