【摘要】 就 Ｍ ｉｎｄｌｉｎ 平板单元的剪切自锁问题进行了探讨并提出了避免自锁的处理方法。文中肋梁采用 Ｔｉｍ ｏｓｈｅｎｋｏ 梁元，故这类加肋板可以考虑横向剪切变形。对几何非线性问题的求解提出了一种效率较高的改进方法。更多还原

【Abstract】 In this paper, the shear locking problem of Mindlin plate element is studied and the method of avoiding locking is put forward. Because Timoshenko beam element is used as the rib, so this ribbed plate discussed here can consider the lateral shear deformation. The improved method of solving nonlinear problem is presented too.更多还原
