Summary:
In this paper, the influence of thermal residual stress on strength and fracture
rotating speed of composite disc is studied and analyzed using finite difference
method and laminated plate theory for two types of reinforced composite discs (radial
fiber reinforced disc and circumferential fiber reinforced disc). As a result the thermal
residĪ¼al stress will reduce radial and tangential stresses in radial fiber reinforced disc,
while it shall increase radial stresses and decrease tangential stresses in
circumferential fiber reinforced disc. The existing of residual stresses in composite
disc will leads to initiation of crack and begins to propagation near the inner diameter
compared to case when neglecting residual stress for cases taken in analysis. It is also
verified that the finite difference method is a good tool for stress analysis of
composite disc under residual stress effect
