| Elastic stresses and failure of rotating cross-ply laminate disks
Kyo-Nam Koo
The Journal of Mechanical Science and Technology, vol. 23, no. 5, pp.1508-1514, 2009
Abstract : Centrifugal force acting on a rotating disk induces in-plane loads in the radial and circumferential directions. An application
of fiber-reinforced composite materials to a rotating disk can satisfy the demand for increasing its rotating
speed. However, previous researches have been confined to single lamina disks. In this paper, a stress analysis of rotating
disks made of multidirectional laminates is performed. The Tsai-Wu failure criterion is applied to the strength analysis
of the rotating laminate disks, from which the maximum allowable speeds are obtained. The cross-ply ratios providing
the maximum allowable speeds are obtained for the glass/epoxy and carbon/epoxy cross-ply laminate disks with
CD geometry.
