摘要
本文应用双三次B样条来构造薄板的横向位移及多种内力的场函数,利用二类变量广义变分原理导出多变量样条元法分析薄板弯曲的系统方程。文中,对系列矩形板的弯曲,作了数值计算,结果表明,本文方法精度高。
A multivariable spline element analysis for plates bending problem is presented in this paper The,bicubic Spline -functions are used to construct the bending moments and transverse displacement's field. The spline element equations with multiply varia-b cs are derived based on Hellinger-Reipsner principle, Some numerical results are qivemand compared with other method.
