摘要
根据厚壁圆筒第一阶段断裂时间的全解耦求法，提出了在小损伤情况下所谓半解耦思路的解答，指出几种典型材料常数情形下两种解答的相对误差值及其变化趋势，并得出全解耦解偏向保守的结论。
In this paper, one new solution for the critical time of the first stage in a thick-walledtube under creep-damage has been deduced.That is one between the uncoupled and coupledmethods.It gives a conclusion:the error the new one relative to the uncoupled one isincreasing nearly linearly with m and n/m increasing, The time from the uncoupled one isconservative.
