| 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. |
