| 摘 要： | 建议了一种较为精确的边界应力求解方法，并用于改进Ｚｉｅｎｋｉｅｗｉｃｚ－Ｚｈｕ（Ｚ２）应力恢复过程。改进过程增加的计算量不大，但可有效地改善后验误差估计精度。ｈ型自适应有限元分析结果表明，改进过程更有利于最优网格寻求工作

| Abstract: | A method is suggested for boundary stress resolution, which is used to improve the Zienkiewicz Zhu(Z 2) stress recovery procedures. The improved procedures can effectively enhance the precision of a posteriori error estimator with less additional computational effort. Results of h daptive finite element analysis show that the improved procedures can make the calculation of optional mesh easier. |
