Nonlinear vibration behavior of a rotating nanobeam under thermal stress using Eringen’s nonlocal elasticity and DQM

摘要: This study is concerned with the small-scale effect on nonlinear flapwise bending vibration of rotating cantilever and propped nanobeams. Euler–Bernoulli beam theory used to model nanobeam nonlinearity. Nonlinear strain–displacement relations are employed account for geometric nonlinearity system. The axial forces modeled as true spatial thermal variations due rotation. Hamilton’s principle derive governing equation nonlocal boundary conditions based Eringen’s elasticity theory. Finally, differential quadrature method in conjunction direct iterative frequencies nanobeam. effects angular velocity, parameter, temperature change amplitude rotary discussed. results this work can be nanosensors, nanomotors, nanoturbines NEMS applications.
