摘要:
精度和收敛问题是有限元分析研究的重点和热点, 而刚体位移对壳单元有限元解的精度和收敛性有
着显著影响, 但学者对位移对壳单元有限元解的精度和收敛性的影响作用有不同的观点, 本文给出了在等参
壳单元有限元分析中补充刚体位移的又一方法, 并通过算例分析说明了刚体位移对壳单元解收敛性和精度
的影响.结果表明刚体位移对壳单元解的收敛性影响明显, 不容忽视.
Abstract:
Rig id body displacements have different form e xisting in shell element trial functio n, a nd the re is differ ent o pinions
about its influe nce .I t is bo rne out by adding rig id bo dy displacements in isoperimetric shell element and solving numerical
ex amples with seve ral me thods , that rigid displacement is so impo rtant fo r the co nv erg ence of shell e lement that
shouldn’ t be neglected .
