Summary: 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.

Summary: In this study, the nonlinear forced vibration analysis of a graphene nanoplatelets reinforced composite (GPLRC) annular plate under hygro-thermal environment and mechanical loading is presented. The research reveals that the moisture change, orientation angle parameter, and rigidity of the boundary conditions affect the structure's frequency. The nonlinear parameter does not have any effects on the maximum amplitudes of resonant vibration. Additionally, decreasing the structure's flexibility can lead to unstable responses.

Summary: This paper investigates a (2+1)-dimensional generalized Burgers system with variable coefficients in a fluid. It obtains the Painleve-integrable constraints of the system with respect to the variable coefficients. Based on truncated Painleve expansions, an auto-Backlund transformation is constructed, along with soliton solutions. Multiple kink solutions are derived using truncated Painleve expansions. Breather solutions, half-periodic kink solutions, and hybrid solutions composed of breathers and kink waves are obtained via complex-conjugate transformation.
