【摘要】 根据数值流形方法的思想，用Ｈｅｒｍｉｔｅ插值函数表示三角形板单元位移模式中的权函数，并在此基础上，在不增加额外覆盖数的条件下，构造了一种新的更高次位移模式，各种条件的计算结果表明这种位移模式具有精度高的优点，很有实用意义．更多还原

【Abstract】 Based on Shi’s numerical manifold method, a new higher order displacement model has been established for a triangular plate bend element, with Hermitian interpolation functions for covers’ weight functions and without adding any other covers. Various numerical examples show that the new model can solve the elastic foundation plate prob- lems and improve the accuracy of deflection and mo-ment.更多还原
