Abstract: In this paper, the fundamental equations of sandwich plate are presented in which the surface is an orthotropic thin plate and the middle layer is also of orthotropic material. Two equations non-coupled are deduced by H's simplified method, which is changed. And moreover, a method is given to calculate w^*,ψ_x^*,ψ_y^* when we want to solve the problem of orthotropic plate by the separating stiffness method.

摘要： 本文在Hoff型理论意义下推导了表层为正交各向异性薄板,夹心为正交各向异性的蜂窝夹层板的基本方程。并推广应用了胡海昌简化方程法,使得方程得以解偶。文章提供了分解刚度法在解正交各向异性板时如何解决D_f=∞时的W^*,ψ_x^*,ψ_y^*的解法。
