| 摘 要： | 基于Hoff型夹层板理论,推导了夹层板广义的应力-应变关系式,得到了等效板的弹性常数,从而建立了考虑表层抗弯刚度的夹层板静力学等效模型.通过理论分析和计算,研究了夹层板的参数对这种等效精度的影响,并给出了这种等效分析方法的适用范围.研究表明,利用等效分析方法对Hoff型夹层板进行静力分析可在一定范围内可达到满意的精度.

| Abstract: | A method of equivalent analysis for statics behavior of sandwich plates was obtained by using Hoff sandwich plate theory,and generalized correlated equations between the stress and strain were derived for the sandwich panel,and equivalent stiffness constants of an equivalent plate were given.By means of analysis in theory and calculation,the influence of the parameters of the sandwich panel on the accuracy of the equivalent method was discussed,and the range of its application was given.The study indicates that the equivalent method can get satisfying precision within the given range. |
