A Modified Couple Stress Theory for Postbuckling Analysis of Timoshenko and Reddy-Levinson Single-Walled Carbon Nanobeams
The novelty of this study is presentation of an exact solution for prediction of postbuckling
behavior of shear deformable micro- and nano-scale beams based on modified couple
stress theory and using principle ...
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 ...
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 ...
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. ...
INVESTIGATION OF FLEXIBILITY CONSTANTS FOR A MULTI-SPRING MODEL: A SOLUTION FOR BUCKLING OF CRACKED MICRO/NANOBEAMS
In this paper, a multi-spring model is used for modelling of the crack in a micro/nanobeam
under axial compressive load based on a modified couple stress theory. This model inc-

Nonlocal modeling and buckling features of cracked nanobeams with von Karman nonlinearity
Buckling and postbuckling behaviors of cracked nanobeams made of single-crystalline nanomaterials are
investigated. The nonlocal elasticity theory is used to model the nonlocal interatomic effects on the beam’s ...
Modeling and Vibration Characteristics of Cracked Nano-Beams Made of Nanocrystalline Materials
A size-dependent Euler–Bernoulli beam model is developed to investigate the vibration characteristics of cracked nano-beams made of nanocrystalline materials. The proposed model incorporates a size-dependent micromechanical ...
