This article presents the amplitude and vibrational characteristics of a rotating fiber metal laminated microdisk. The current microstructure is modeled using a two-parameter viscoelastic foundation and the centrifugal and coriolis effects due to rotation are considered. The strains and stresses are determined using the third-order shear deformable theory and the nonlocal strain gradient theory is used to access size-effects. The boundary conditions are derived through governing equations of the laminated rotating microdisk using Hamilton's principle and solved using a numerical method based on the generalized differential quadrature method.
In this article, amplitude, and vibrational characteristics of a rotating fiber metal laminated microdisk are presented. The current microstructure is modeled as a flexible microdisk surrounded by the two-parameter viscoelastic foundation. The centrifugal and coriolis effects due to the rotation are considered. The strains and stresses can be determined via the third-order shear deformable theory. For accessing to size-effects, the nonlocal strain gradient theory is used. The boundary conditions are derived through governing equations of the laminated rotating microdisk using an energy method known as Hamilton's principle and finally are solved using a numerical method based generalized differential quadrature method.
