摘要
基于块平衡恢复技术并考虑界面热阻进行了铸造系统非线性瞬态热传导问题的自适应有限元分析 ,同时采用超收敛块光滑技术及ANSYS软件对我们自编的软件进行了验证。三种有限元解与实验结果比较表明 。
Recovery by equilibrium in patches (REP) technique is adopted for the non\|linear transient heat conduction adaptive FEM analysis of casting system, which takes account of thermal conductivity of the interface. In order to test the present program, ANSYS and superconvergent patch recovery (SPR) methods are also employed for analysing the same problem respectively. The results of numerical analysis are compared with the experiment results, which show that REP method is cost effective. [
