摘要
将双参数弹性地基上中厚板离散为有限元线法单元 ,通过对地基 板系统势能泛函进行变分 ,推导出其弯曲问题的有限元线法方程 ,对数值算例编程求解 ,得出较满意结果并与其他文献进行比较 ,为双参数弹性地基上中厚板弯曲问题的分析 ,提供了一种新的半解析数值方法。
Based on the theory of the finite element method of lines,a middle?thick bending plate on two?parameter elastic foundation is studied in the paper The variation of the potential energy functional of the platesfoundation system is obtained;then the equation of a bending plate is derived At same time,a program is developed to solve the bending plate The computing results are well agreed with that of the data from other references It will be seen from this that a new semi?analytical numerical method is proposed to solve such kind of problems
