Dynamic behavior of nanobeams under axial loads: Integral elasticity modeling and size-dependent eigenfrequencies assessment
摘要：
在这篇文章中，本征频率下的轴向载荷的纳米梁进行评估，使诉诸适定的应力驱动的非局部模型（SDM）和应变驱动的两个阶段的本地/非本地制定（NstrainG）的弹性和Bernoulli-Euler运动学。所开发的非局部方法适用于各种各样的纳米工程材料，如碳纳米管，和现代小规模的纳米技术感兴趣的梁状装置。利用SDM计算的本征频率，NstrainG和其他相关文献中的其他非局部策略得到的结果进行了比较。分析和讨论了非局部热弹性效应和初始轴力（拉、压）对结构动力响应的影响。模型硬化尺寸效应从应力驱动的方法进行了比较，从应变驱动的两个阶段的本地/非本地的方法增加非本地参数的模型软化尺寸效应。
英文摘要：
In this article, eigenfrequencies of nano-beams under axial loads are assessed by making recourse to the well-posed stress-driven nonlocal model (SDM) and strain-driven two-phase local/nonlocal formulation (NstrainG) of elasticity and Bernoulli-Euler kinematics. The developed nonlocal methodology is applicable to a wide variety of nano-engineered materials, such as carbon nanotubes, and modern small-scale beam-like devices of nanotechnological interest. Eigenfrequencies calculated using SDM, are compared with NstrainG and other pertinent results in literature obtained by other nonlocal strategies. Influence of nonlocal thermoelastic effects and initial axial force (tension and compression) on dynamic responses are analyzed and discussed. Model hardening size effects from stress-driven approach is compared to model softening size effects from strain-driven two-phase local/nonlocal approach for increasing nonlocal parameters.
