摘要：

This article is concerned with the modeling and analysis of symmetrical vibrations of composite sandwich panels. The vibration problem is solved for the sandwich plate with identical composite facings and orthotropic core. The solution is based on the use of the model that takes into account compressive and shear stiffnesses, and nonlinear distribution of transverse normal displacements over the core thickness. The equation is obtained for the calculation of symmetric vibration frequency of the sandwich plate with simply supported facings. The effects of elastic, geometric, and inertia parameters on the frequencies of symmetric vibrations are investigated.
