Abstract EN
Crack changes the dynamic characteristics of the vibrating body such as the natural frequencies and stiffness of the system.
Now a day many researchers are studying on the cracks in the structures made of composite material because are being used more than past due to their great mechanical properties such as their high strength to weight ratio.
This study presents theoretical, numerical (FEM), and experimental analysis of a cantilever composite beam with double transverse crack.
Carbon fiber- Epoxy has been taken as the material for this study.
Several factors play grate and important rules in vibration response and natural frequencies of the cracked composite beams.
This work presents dynamic responses of double-cracked composite beams at different fiber volume fraction and angles.
The numerical results were found in good agreement with experimental and analytical results.
The study concludes that the existence of double crack in composite structure with different fiber volume fraction and angles can be diagnosed by using vibration signatures, and it useful for monitoring the health of the composite structures
