UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe bending problem of functionally graded Bernoulli–Euler nanobeams is analyzed starting from a nonlocal thermodynamic approach and new nonlocal models are proposed. Nonlocal expressions of the free energy are presented, the variational formulations are then consistently provided and the differential equations with the associated higher-order boundary conditions are derived. Nonlocal Eringen and gradient elasticity constitutive models are recovered by specializing the variational scheme. Examples of nanobeams are explicitly carried out, detecting thus also new benchmarks for computational mechanics.
