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…

Nonlocal strain gradient torsion of elastic beams: variational formulation and constitutive boundary conditions
R. Barretta, S. Ali Faghidian, F. Marotti de Sciarra +1
Nonlocal strain gradient continuum mechanics is a methodology widely employed in literature to assess size effects in nanostructures. Notwithstanding this, improper higher-order bo…
