正交各向异性板受力偶作用时的响应

力偶分为静力偶和动力偶。本将静力偶以等值、反向、平行且相距很近的两个力等效代替，用加权残值法给出了静力偶作用下薄板弯曲的挠度计算；用拉格朗El方程建立了动力偶作用下薄板的运动微分方程，并给出其动力响应。

Response of Perpendicular Heterogeneous Slab under the Action of Couple

The couple includes static and dynamic one. In this article, the static couple is substituted for two equivalent, reverse and parallel forces with close interval. The flexible calculation of bending lamella under the action of static couple is deduced by the method of weighted residual. And differential equation of motion of lamella under the action of dynamic couple is set up by means of Lagrange's equation. In the end, its dynamic response is presented here.
