Vibrações de placas sandwich enrijecidas por barras conectoras

Analysis of the free transverse vibration equations of retangular sandwich-type plates including spaced transverse posts between the faces which introduce additional stiffness in the core, under compressive uniforme load acting in the midplane, as well as the determination of the critical loads by a dynamical process. The equations of vibration were obtained through the substitution of the constitutive equations into the equations of motion. Some results, as the variation of the natural frequencies and critical loads with the shear stiffness of the plate changing the sizes of the transverse posts were plotted. It is also plotted the influence on the critical load of the vibration mode and the transverse posts stiffness.
