Damping of composite material structures with bolted joints

Abstract

In the present work, the damping in composite structures with bolted joint has been extensively studied by the use of finite element analysis model. The various operations viz. modal, harmonic response and transient dynamic analyses are stimulated to find out different results in ANSYS and calculations were done as per the results from ANSYS to find further results. The parameters related to damping in composite bolted joints are found. It has been inferred from the paper that damping in composite bolted joint is very high. Rayleigh’s damping constants and loss factor in the structure has also been calculated. A detailed mathematical and analytical model has been presented for understanding damping better. This topic of research is beneficial for various upcoming and ongoing products in the market.
