In the current work, for first time, bending and vibration information of axisymmetric thick annular nanoplate made laminated composite layers is studied. The structure placed on Winkler-Pasternak substrate with elastic tortional coefficients. Initial stress as an external load also considered in structure. For modeling mechanical deformation layer-wise materials, zigzag theory that its functions themselves are continues interface presented. By coupled quasi-3D new refined (Q3D-NRT) nonlocal strain gradient used obtaining nonclassical governing equations a general boundary condition nanoplate. Also, static dynamic nanostructure, Hamilton's, Minimum total potential energy principles used, respectively. Via differential quadrature method weighting factors nth-order derivative, aid size-dependent conditions solved. comparing results outputs previous reports, accuracy shown.
