摘要

本文对温克勒-帕斯捷尔纳克地基上功能梯度纳米片中的波传播特性进行了分析。在非局部弹性理论和包含不定积分项的四未知高阶位移理论的框架下进行了研究。利用Hamilton原理和Navier方法求解特征值问题，得到了不同条件下FG纳米片的频率关系。所得的波在FG纳米片中的传播频率和相速度的结果与最近的类似研究结果进行了比较。

Wave Propagation in Functionally-Graded Nanoplates Embedded in a Winkler–Pasternak Foundation with Initial Stress Effect

This paper presents the analysis of wave propagation in functionally-graded (FG) nanoplates on a Winkler–Pasternak foundation. The investigation is carried out in the framework of nonlocal elasticity theory and a new four-unknown higher-order displacement theory including indeterminate integral terms. Hamilton’s principle and Navier’s method are used to obtain the frequency relations of FG nanoplates for different conditions by solving an eigenvalue problem. The obtained results for the frequency and phase velocity of wave propagation in an FG nanoplate are compared with recent outcomes of similar research.
