摘要:
作者介绍了基于广义变分原理的各种有限元杂交法在实体结构中的实施方案。在分析一些实例计算结果的基础上,建议采用一种位移/杂交混合计算法。误差分析及例题计算的结果表明,采用此方法计算应力时,其精度与杂交法同阶,但所需计算时间比杂交法少。
Abstract:
In view of the facts, that the conventional hybrid element method is more sophisticated and requires more computer time for practical application, the authors propose some schemes for implementing the hybrid element for solid bodies based on the generalized variational principles. Having investigated the results of the calculation of some typical examples, the authors suggest a displacement/hybrid element mixed method. The error analysis and the numerical evaluations show that, in the stress calculation by using the mixed method, the accuracy obtained is of the same degree as that obtained by the conventional hybrid method and less computer time is required in mixed method. It is obvious that the presented mixed method is worth of further study and application.
