Eringen’s nonlocal and modified couple stress theories applied to vibrating rotating nanobeams with temperature effects

This study develops a comprehensive vibrational analysis of rotating nanobeams on visco-elastic foundations with thermal effects based the modified couple stress and Eringen’s nonlocal elasticity theories. approach accurately simulates size effects. Higher-order shear deformation beam theory generalized differential quadrature method are used to obtain numerical results. The parameters, length scale, Winkler–Pasternak coefficients, gradient, slenderness ratios, velocity, viscoelastic coefficient demonstrated discussed in detail. Mode switching importance correct choice associated effect parameters highlighted.
