Size-dependent dynamic pull-in analysis of beam-type MEMS under mechanical shock based on the modified couple stress theory
couple stress theory (MCST) with von
Kármán-type geometric non-linearity is utilized in theoretical formulations. The non-linear
governing differential equation of motion is derived using Hamilton’s principle and solved
using a simple...
Postbuckling of functionally graded nanobeams based on modified couple stress theory under general beam theory
In this paper, analysis of shear deformable functionally graded (FG) nanobeams in postbuckling based on
modified couple stress theory is presented. The nonlinear behavior of postbuckling is defined based on
von-Karman geometric...
An investigation of stress wave propagation in a shear deformable nanobeam based on modified couple stress theory
This paper presents a new investigation for propagation of stress wave in a nanobeam based on modified couple stress theory. Using Euler– Bernoulli beam theory, Timoshenko beam theory, and Reddy beam theory, the effect of shear deformation...
BUCKLING AND POSTBUCKLING OF SIZE-DEPENDENT CRACKED MICROBEAMS BASED ON A MODIFIED COUPLE STRESS THEORY
The elastic buckling analysis and the static postbuckling response of the Euler–Bernoulli microbeams containing an open edge crack are studied based on a modified couple stress theory. The cracked section is modeled by a massless elastic rotational...
A MULTI-SPRING MODEL FOR BUCKLING ANALYSIS OF CRACKED TIMOSHENKO NANOBEAMS BASED ON MODIFIED COUPLE STRESS THEORY
This paper develops a cracked nanobeam model and presents buckling analysis of this developed model based on a modified couple stress theory. The Timoshenko beam theory and simply supported boundary conditions are considered. This nonclassical model...
The Influence of Couple Stress Components and Electrostatic Actuation on Free Vibration Characteristics of Thin Micro-Plates
stress theory. To this end, a Kirchhoff’s thin plate model together with the modified couple stress theory is considered to extract the eigenvalue problem which governs on free vibrations of the system. Using the free vibration equation of the system...
Analytical determination of size-dependent natural frequencies of fully clamped rectangular microplates based on the modified couple stress theory
This paper presents an analytical and size-dependent model for vibrational analysis of fully clamped rectangular microplates. Modified couple stress theory (MCST) and the Kirchhoff plate model are considered, and Hamilton’s principle is employed...
An analytical solution for thermoelastic damping in a micro-beam based on generalized theory of thermoelasticity and modified couple stress theory
This paper is aiming to present an analytical method to study on thermoelastic damping (TED) and dynamic behavior of micro-beam resonators as a micro-electro-mechanical system (MEMS) using modified coupled stress theory. Coupled thermoelasticity...
