传热场问题的界面元法

用界面元法求解场问题，导出了求解三维不稳定温度场的界面元计算公式，这些公式适用于连续及不连续温度场，能反映介质可能存在的温度不连续性，较以往数值方法具有精度高、基本未知量少、适用于任意形状单元的优点，为温度场与位移场、应力场的耦合奠定了基础。

Rigid Body Surface Element Method in Analysis of Thermal Field Problems

The Rigid Body Surface Element Method (RBSM) in the analysis of thermal field problems has been discussed in this paper.Corresponding formulae for solving 3 dimensional problems have been presented.The algorithm can be applied to both continuous and discontinuous field problems.Possible thermal discontinuity in the media can be properly reflected.Compared with other numerical methods,RBSM has such advantages as high accuracy,few unknowns and arbitrary elements.RBSM provides a basis for the coupling with displacement field and stress field.
