摘要:
将GSQ24壳体单元用于板壳与梁和实体结构的组合分析,在不同类型单元联结交界处,通过位移协调条件建立的几何约束方程直接引入到壳体单元的刚度矩阵和载荷向量中,给出了相应有限元列式.算例结果表明了本文方法的合理性和通用性.
Abstract:
GSQ24 shell element is used in analysis of combination of plates and shells,beam and three-dimentional solid structures.On joint boundary of different types of elements,equations of geometric restrictions,formed by displacement conforming,are introduced to the GSQ24 shell element stiffness matrices and load vectors directly,and corresponding FEM formulae are given.The results of numerical examples show that the present method is feasible and versatile.
