摘要

研究探讨了纵波在轴向分级纳米管中的传播。使用非局部雷勒-毕晓普杆理论考虑了剪切变形和横向惯性对纳米棒的影响。作为一种新方法，在分级公式中假设了一个非局部参数。利用高阶哈小波法求解支配运动方程。研究了材料分级幂律指数和非局部参数对轴向分级纳米棒纵波响应的影响。得到了轴向分级纳米棒的相位和群速度变化。本研究可能有助于先进功能复合纳米线的建模。

Longitudinal Wave Propagation in Axially Graded Raylegh–Bishop Nanorods

Longitudinal wave propagation in axially graded nanotubes was explored. The effect of shear deformation and lateral inertia on nanorods was considered using the nonlocal Raylegh–Bishop rod theory. As a novel approach, a nonlocal parameter was assumed in the graded formulation. The higher order Haar wavelet method was utilized for solving the governing equation of motion. The effects of material grading power-law index and nonlocal parameters on the longitudinal wave response of axially graded nanorods were investigated. Phase and group velocity variations of the axially graded nanorod were obtained. The present study may be useful in the modeling of advanced functional composite nanowires.
