چکیده مقاله:
Vibration analysis of piezoelastic cylindrical nanoshell (PCNS) subjected to visco-Pasternak medium with arbitrary boundary conditions is investigated using Eringen nonlocal theory and considering Donnell s shell theory and Hamilton’s principle. The viscoelastic nanoshell medium is modeled as Visco-Pasternak foundation. The convergence, accuracy and reliability of the current formulation are validated by comparisons with existing experimental and numerical results. Also, the effects of nonlocality are accurately studied on frequencies of piezoelastic cylindrical nanoshell.
