用非协调有限元方法解决应力边界条件下平面弹性问题Locking现象,给出了新的非协调有限元格多,证明了此格式的收敛性,并给出了最优的误差估计.
The locking phenomenon for the planar elastic problem under the boundary condition of stress is studied by applying the non - harmonic finite element method. A new format of the non - harmonic finite element is obtained, and the convergence of the new format is proven. Moreover, the optimum error estimate is also given.
