ANALYSIS OF COMPOSITE ROTATING DISCS
Keywords:
Composite Material, Rotating Disc, Fiber ReinforcementAbstract
The effects of centrifugal forces on stresses and deformations are important for the design of rotating discs. The disc is made out of composite laminate plate which is considered to be specially orthotropic. Different composite materials with different laminate sequences have been used for investigating the radial and tangential stress resultants in addition to displacements. Classical laminate plate theory is used in the analysis to study the effect of anisotropy on the rotating disc stress distribution. Stresses and displacements are also found from the Finite Element Software. .A stiffness ratio is defined as the ratio of circumferential stiffness to radial stiffness and this is used as a parameter to represent the degree of anisotropy. Results obtained from this investigation for stresses and displacements have been tabulated and presented graphically. These results are useful for the design of rotating discs.
