用刚体界面元法分析温度场、温度应力及徐变应力

Rigid-Body Interface Element Method (RIEM) in analysis of thermal field thermal stress and creeping stress

本文用刚体界面元法推导了求解温度场问题的方程，算法适用于连续及不连续温度场，建立了刚体界面元法求解温度应力及徐变应力的公式，算例表明本文算法是合理可行的，具有一定的应用价值．

Formulae for solving thermal field problems have been derived using RIEM, which can be used for both continuous and discontinuous thermal field problems. Formulae for solving thermal stress and creeping stress have been presented as well. Numerical examples show that the methods in this paper are reasonable and feasible.
