本文从一修正的变分原理出发,以胡海昌导出的关于Reissner板弯曲方程的两个位移函数为中间变量,推导出弹性地基板的一个完备解系及其相应的杂交-Trefftz有限元公式.文末给出的算例验证了本数值模型的可靠性和有效性.
In this paper, starting from a modified variational principle, the two displacement functions of the Reissner plate bending equation derived by Hu Haichang are used as intermediate variables to derive a complete solution of the elastic ground plate and its corresponding hybrid-Trefftz finite element formula. The given examples verify the reliability and effectiveness of the numerical model.
