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 ...

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 model and Mindlin...

In this paper, thermoelastic damping in a nano-beam is studied employing the type III of

Green-Naghdi (GN) theory (with energy dissipation). The nano-beam is considered as a beamtype

of NEMS (nano-electro-mechanical systems). A...
