摘要
针对中厚板弯曲分析问题,根据数值流形方法的特点及位移模式,对求解中厚板流形单元的覆盖位移函数、应变矩阵及刚度矩阵进行详细推导,并在Winkler弹性地基上建立Mindlin板流形单元的控制方程。最后通过计算表明,该法在弹性地基上中厚板的弯曲分析中是有效的。
Based on the displacement model and the characters of numerical manifold method, the cover displacement function, the strain matrix and the stiffness matrix in manifold element of moderately thick plate are derived for plate bending problems analysis. The controlling equation of Mindlin plate manifold element on Winkler elastic foundation is achieved. The calculation result shows the validity of the plate bending analysis of elastic foundation.
