摘要: In this paper, the free vibration and torsional static analysis of cylindrical shell are developed using modified strain gradient theory. doing this, governing equations classical non-classical boundary conditions derived Hamilton’s principle. After obtaining problem, differential quadrature method is used to discretize motion problem examine single-walled carbon nanotube (SWCNT) with two clamped-free clamped–clamped supports as a special application formulation. Also, carried out for SWCNT. Results reveal that SWCNT rigidity in theory higher than couple stress or theory, which leads increase frequencies decrease torsion also demonstrate effect size parameter different lengths diameters considerable.
