根据叠加原理将含有椭圆形内部分层的层板在横向载荷作用下的受力状态进行分解 ,从而将分层问题归结为在分层表面上的附加剪切载荷作用下层板附加位移与附加应力的分析 ,并据此建立了一个仅包含分层区的力学模型。然后利用双三角级数构造满足层板分层区位移边界条件的位移模态。最后 ,应用最小势能原理确定位移解。计算结果收敛 ,挠度收敛尤为迅速。 According to the principle of superposition, the stress state of laminates containing elliptical internal laminates under the lateral load is decomposed, and the laminarization problem is attributed to the additional displacement and additional stress of the laminates under the additional shear load on the laminar surface Based on this, a mechanical model that includes only stratified zones has been established. Then, using the double trigonometric series to construct the displacement modal that satisfies the displacement boundary conditions of layered zone. Finally, the displacement solution is determined using the principle of minimum potential energy. The calculation results converge, and the deflection converges especially rapidly.
