提出了弹性基础上雷氏板分析的改进变分原理。基础可能是温克勒型或帕斯捷尔纳克型。基于该原理和一组新的t完全函数建立了一种混合Trefftz （HT）有限元模型。通过数值算例验证了所提方法的有效性。
A modified variational principle for analysis of Reissner plates on an elastic foundation is presented. The foundation may be of Winkler type or Pasternak type. A hybrid Trefftz (HT) finite element (FE) model has been developed based on the principle and a new set of T-complete functions. Several numerical examples are considered to assess the effectiveness of the proposed method.
