The method uses a general formulation for steady-state creep deformation for multi-material components in conjunction with the results of FE analyses. The practical application of the proposed technique, in determining the secondary creep properties of heat-affected zone (HAZ) materials in welds, for which conventional creep testing methods cannot be used, is considered. A number of numerical examples are used to describe solution procedures and to verify the method. 关 键 词：焊接接头 焊接热影响区 疲劳 蠕变 有限元 数值模拟 压痕试验 焊接材料
