瑞斯纳 meaning in English

reissner-hellinger principle

The elastic foundation model is considered as two - parameter elastic foundation model and its effect to moderate - thick plates are taken into account by a set of governing differential equations . united with hu hai - chang ’ s function , least squares collocation weighted residual method which uses b - spline function as trial function is put forward for solving the bending problems . compare with the results of finite element method of lines , spline finite strip method , accurate solution of series etc . it is proved that the method in this article has adequate accuracy and practical feasibility
本文采用瑞斯纳中厚板理论求解弹性地基板,建立双参数地基与中厚板相互作用的控制微分方程,结合胡海昌的解耦函数,运用双五次b样条函数作为试函数的离散型最小二乘加权残值法分析了双参数地基上的中厚板的弯曲问题,并将结果与有限元线法、有限条法、级数精确解等进行比较,证明本文方法具有足够的精确性与实际的可行性。
