Free Vibration Analysis of the Strengthened Beams by Composite Coats

Abstract:

The analysis of free vibration of simply-supported lamineted composite coated beams is investigated. With a core made from an isotropic material (steel) and faces made from composite material, (glass/epoxy and carbon/epoxy), two sandwich beam models are used in the study. For this purpose, a computer code is developed using MATLAB to perform the analysis of free-vibration of strengthened beams by composite coats. The effects of the variation of different parameters such as the span/depth ratio, fiber orientation angle of the coat, and thickness ratio on natural frequencies and of the beam are examined.
