Vibration analysis of fiber reinforced composite discs

Abstract

The present paper focuses on the dynamic behavior of fiber reinforced composite discs. Rotating discs are an important sub-component of any rotor dynamic system. Variation of natural frequencies for different fiber reinforcement configurations against rotational speed due to stress stiffening effect has been studied in detail. Critical Speed of various configurations has been examined. Tsai-Wu failure criterion has been applied to examine the bursting speed of composite disc. Useful results are obtained for rectilinear orthotropic reinforcement of rotating disc.
