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 ...

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 ...

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 ...

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. ...

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-

ludes an equivalent rotational ...

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 ...

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 ...

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 ...
