Abstract

Dynamic behavior of hybrid composite shallow shell panels was analyzed utilizing a high-order shear deformation theory (HOSDT) in conjunction with the finite-element method (FEM). To enhance the suitability of plant-fiber composites and to use them as substitutes for pure synthetic-fiber composites, the hybridization of banana-epoxy and glass-epoxy composites was performed, and different sets of hybrid composites were prepared by altering the layers of glass and banana fibers. The elastic constants of these composites were evaluated experimentally and utilized in the further numerical investigation. Simultaneously, a mathematical formulation was developed based on a HOSDT and the FEM. The governing equation of a transient analysis was derived using the Hamilton’s principle and Newmark’s direct integration scheme to get responses in the time domain. First, the consistency of the present model was checked via an element convergence test, and the accuracy of the model was established by comparing the transient responses obtained from the current model with those of published data. Afterwards, different parametric investigations were carried out to explore the influence of the curvature ratio, shell geometry, hybridization, end conditions, and loading rate on the time-dependent responses of the composites.

混合复合材料壳体面板在动态载荷下的挠度行为
利用高阶剪切变形理论(HOSDT)和有限元方法(FEM)分析了混合复合材料浅壳板的动态行为。为了提高植物纤维复合材料的适用性并将其用作纯合成纤维复合材料的替代品,研究人员对香蕉-环氧和玻璃-环氧复合材料进行了杂化,并通过改变玻璃纤维和香蕉纤维的层数制备了不同的混合复合材料。实验评估了这些复合材料的弹性常数,并将其用于进一步的数值研究。同时,在 HOSDT 和有限元模型的基础上开发了数学公式。利用汉密尔顿原理和纽马克直接积分方案推导出瞬态分析的控制方程,从而得到时域响应。首先,通过元素收敛测试检验了当前模型的一致性,并通过比较当前模型获得的瞬态响应和已公布的数据,确定了模型的准确性。随后,进行了不同的参数研究,以探讨曲率比、壳体几何形状、杂交、端部条件和加载速率对复合材料随时间变化的响应的影响。
