摘要

采用Chebyshev-Ritz-Bolotin方法对梯度多孔纳米板的动态稳定性进行了数值模拟和计算机模拟。根据非局部弹性和捕获中性表面位置的3-未知板模型，制备了纳米板。假定材料的所有性能都取决于孔隙率因子，孔隙率因子决定了孔隙的数量或体积。在温度和湿度变化的条件下，也假设了纳米板。结果表明，纳米板的稳定性边界取决于静、动载荷因素、孔隙率因素、温度变化和非局部参数。

A numerical and computer simulation for dynamic stability analysis of 3-unknown graded porous nanoplates using a Chebyshev-Ritz-Bolotin method

A numerical and computer simulation for dynamic stability analysis of graded porous nanoplates has been provided using a Chebyshev-Ritz-Bolotin approach. The nanoplate has been formulated according to the nonlocal elasticity and a 3-unkown plate model capturing neutral surface location. All of material properties are assumed to be dependent of porosity factor which determines the amount or volume of pores. The nano-size plate has also been assumed to be under temperature and moisture variation. It will be shown that stability boundaries of the nanoplate are dependent on static and dynamical load factors, porosity factor, temperature variation and nonlocal parameter.
