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...
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...
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...
Bending analysis of size- dependent functionally graded annular sector microplates based on the modified couple stress theory
In the present paper, a non-classical model for functionally graded annular sector microplates under distributed transverse loading is developed based on the modified couple stress theory and the first-order shear deformation plate theory. The model...
Thermal and mechanical buckling analysis of FG carbon nanotube reinforced composite plates using modified couple stress theory and isogeometric approach
This paper investigates the thermal and mechanical buckling analysis of functionally graded carbon nanotube
reinforced composite (FG-CNTRC) plates by using isogeometric analysis (IGA) based on modified couple stress theory (MCST). A refined...
