Modeling of nonlocal porous functionally graded nanobeams under moving loads

Научно-технический вестник информационных технологий, механики и оптики
This study focuses on the dynamic response of porous functionally graded nanomaterials to moving loads. The analysis was performed using two approaches: the Ritz method with the help of the benefits achieved by employing Chebyshev polynomials in the ...

New observations on transverse dynamics of microtubules based on nonlocal strain gradient theory

Composite Structures, 2019
Abstract Based on nonlocal strain gradient theory, we present dynamical behaviors of a microtubule subjected to axial load, thermal load and variable transverse load simultaneously. The existing nonlocal strain gradient constitutive relation is adjusted from the perspective of dimensional analysis for better understanding and application, especially ...

Geometrically Nonlinear Electromechanical Instability of FG Nanobeams by Nonlocal Strain Gradient Theory

International Journal of Structural Stability and Dynamics, 2021
This paper is concerned with studying the size-dependent nonlinear dynamic pull-in instability and vibration of functionally graded Euler–Bernoulli nanobeams (FG-EBNs) with the von Kármán hypothesis based on the nonlocal strain gradient theory (NLSGT). To this end, the partial differential equation (PDE) is developed by Hamilton’s principle considering

Contribution of nonlocal integral elasticity to modified strain gradient theory

The European Physical Journal Plus, 2021
The nonlocal integral elasticity and the modified strain gradient theory are consistently integrated in the framework of the nonlocal modified gradient theory of elasticity. The equivalent differential formulation of the constitutive law, equipped with appropriate nonstandard boundary conditions, is introduced.
