On nonlocal mechanics of curved elastic beams
Raffaele Barretta, Francesco Marotti de Sciarra, Marzia Sara Vaccaro
Curved beams are basic structural components of Nano-Electro-Mechanical-Sistems (NEMS) whose design requires appropriate modelling of scale effects. In the present paper, the size-…
Random vibrations of stress-driven nonlocal beams with external damping
Francesco Paolo Pinnola, Marzia Sara Vaccaro, Raffaele Barretta +1
Stochastic flexural vibrations of small-scale Bernoulli-Euler beams with external damping are investigated by stress-driven nonlocal mechanics. Damping effects are simulated consid…
Variationally consistent dynamics of nonlocal gradient elastic beams
Francesco P. Pinnola, S. Ali Faghidian, Raffaele Barretta +1
The variational static formulation contributed in [International Journal of Engineering Science 143, 73-91 (2019)] is generalized in the present paper to model axial and flexural d…
Timoshenko nonlocal strain gradient nanobeams: Variational consistency, exact solutions and carbon nanotube Young moduli
Raffaele Barretta, S. Ali Faghidian, Francesco Marotti de Sciarra +1
Carbon nanotubes (CNTs) are principal constituents of nanocomposites and nano-systems. CNT size-dependent response assessment is therefore a topic of current interest in Mechanics…
On thermomechanics of multilayered beams
Raffaele Barretta, Marko Čanađija, Francesco Marotti de Sciarra
In this paper, the mechanical behavior of multilayered small-scale beams in nonisothermal environment is investigated. Scale phenomena are modeled by means of the mathematically we…
A stress-driven local-nonlocal mixture model for Timoshenko nano-beams
Raffaele Barretta, Andrea Caporale, S. Ali Faghidian +3
A well-posed stress-driven mixture is proposed for Timoshenko nano-beams. The model is a convex combination of local and nonlocal phases and circumvents some problems of ill-posedn…
