Linear dynamic response of nanobeams accounting for higher gradient effects

Linear dynamic response of nanobeams accounting for higher gradient effects

Linear dynamic response of simply supported nanobeams subjected to a variable axial force is assessed by Galerkin numerical approach. Constitutive behavior is described by three functional forms of elastic energy densities enclosing nonlocal and strain gradient effects and their combination. Linear...
