基于经典壳理论,研究了弹性地基上功能梯度碳纳米管增强复合材料(FG-CNTRC)截锥壳在动载荷作用下的线性动力响应.截头圆锥形壳体由根据壳体厚度的线性函数变化的单壁碳纳米管(SWCNT)增强。运动方程分别用Galerkin法和四阶龙格-库塔法求解。在数值计算中,研究了几何参数、弹性地基、固有频率参数和碳纳米管体积分数对FG-CNTRC截锥壳的影响。通过与其他作者的结果进行比较,验证了所提出的结果。
Based on the classical shell theory, the linear dynamic response of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) truncated conical shells resting on elastic foundations subjected to dynamic loads is presented. The truncated conical shells are reinforced by single-walled carbon nanotubes (SWCNTs) that vary according to the linear functions of the shell thickness. The motion equations are solved by the Galerkin method and the fourth-order Runge–Kutta method. In numerical results, the influences of geometrical parameters, elastic foundations, natural frequency parameters, and nanotube volume fraction of FG-CNTRC truncated conical shells are investigated. The proposed results are validated by comparing them with those of other authors.
