利用样条小波的小波尺度函数构造了三角形和矩形薄板单元的位移插值函数。然后用样条小波函数表示位移形函数。利用虚功原理建立了薄板弯曲的样条小波有限元列式。两个数值算例表明,用该方法计算的薄板弯曲挠度和弯矩与微分方程和常规单元的计算结果符合得很好。结果表明,现有的样条小波有限元方法具有较高的数值精度和收敛速度。建议的样条小波有限元公式具有广泛的适用性,因为它是以相同的方式开发,像传统的基于位移的有限元。
The wavelet scaling functions of spline wavelets are used to construct the displacement interpolation functions of triangular and rectangular thin plate elements. The displacement shape functions are then expressed by spline wavelet functions. A spline wavelet finite element formulation of thin plate bending is developed by using the virtual work principle. Two numerical examples have shown that the bending deflections and moments of thin plates agree well with those obtained by the differential equations and conventional elements. It is demonstrated that the current spline wavelet finite element method (FEM) can achieve a high numerical accuracy and converges fast. The proposed spline wavelet finite element formulation has a wide range of applicability since it is developed in the same way like conventional displacement-based FEM.
