我们提出的增强型分片检验可以用于检验一类非齐次阶微分方程的有限元的收敛性.由此,建立了常规轴对称问题和轴对称偶应力/应变梯度C1理论有限元增强型分片检验的检验函数,并得到重要结论:这类轴对称有限元的分片检验函数不含常剪应力项.
The enhanced patch test proposed by us can be used to test the convergence of the finite element of a class of nonhomogeneous differential equations. As a result, the conventional axisymmetric problems and the axially symmetric even-stress / strain gradient C1 finite element enhanced finite element method Fragment test test function, and got the important conclusion: Such axisymmetric finite element fragment test function does not contain the term of normal shear stress.
