| 摘 要： | 基于薄板的小挠度理论,根据四边简支矩形薄板在横向变温作用下的挠度和内力解答,通过应用虚功原理和叠加原理,推导了三边简支一边固支矩形薄板在横向变温作用下的挠度方程和内力解析解,从而为以后的工程计算提供了理论依据。

| Abstract: | Based on the small deflection plate theory,according to the deflection and internal force of rectangular thin plate with four simply supported edges under temperature variation which is perpendicular to surface,the analytical solution about deflection and internal force of rectangular thin plate with three simply supported edges and one clamped edge under temperature variation which is perpendicular to surface was derived for isotropic materials through virtual work principle and superposition principle,and so a theoretical base is provided for subsequent engineering calculation. |
