| 摘 要： | 有限元方法是一种便捷、强大的分析方法,常用于解决工程设计和研究中的各种复杂问题,但作为一种逼近的数值分析方法,其计算结果存在一定的误差,需要利用合理的误差评估方法评价有限元解并为进一步的改进提供依据.因此,将SPR误差评估嵌入弹塑性有限元静力数值分析中,验证在该计算中SPR误差评估的可靠性,并应用于相应的流弹塑性的动力分析中,为进一步优化网格、改进有限元计算结果提供依据.

| Abstract: | FEM is a convenient and powerful method,always employed to all kinds of complicated problems in the design and study of engineering.However,as an approximate numerical method,the FEM results have some errors,which should be improved based on some reasonable error estimation methods.Therefore,an SPR error estimation is implanted into the static FEM numerical analysis against elasto-plastic constitutive model,to gain a verification of reliability of the SPR error estimation.Also the SPR error estimation is applied to the fluidal elasto-plastic dynamic analysis and some basis is offered to improve FEM. |
