摘要: Abstract A size-dependent nonlinear nonlocal strain gradient model for nanoscale tubes is proposed in this investigation and the forced mechanical behaviour examined. This continuum better capable of incorporating size effects as it includes two independent length-scale parameters. The scale-dependent elastic energy motion well work carried out by excitation load are formulated. non-classical differential equation tube obtained using Hamilton's work/energy principle together with elasticity. precise numerical solution presented dynamic characteristics within framework Galerkin's scheme conjunction a continuation approach. influences nanosystem parameters such scale parameters, length-to-gyration-radius ratio amplitude force on frequency/force responses explored discussed details.
