Reissner-Mindlin板問(wèn)題的新連續(xù)有限元方法
發(fā)布時(shí)間:2021-03-24 03:51
基于三角形網(wǎng)格和四邊形網(wǎng)格,分別通過(guò)增加Galerkin公式和修正板厚,提出了求解Reissner-Mindlin板問(wèn)題的兩類新的有限元方法.在這兩類方法中,橫向位移用協(xié)調(diào)(雙)線性宏元或(雙)二次元逼近,旋度用協(xié)調(diào)(雙)線性元逼近.剪切應(yīng)力可以由橫向位移和旋轉(zhuǎn)進(jìn)行局部計(jì)算.在自然范數(shù)下,我們得到橫向位移,旋度和剪切應(yīng)力關(guān)于板厚的一致性的最優(yōu)誤差界.數(shù)值結(jié)果說(shuō)明了理論的正確性和方法的有效性.
