Abstract : "Creep stresses and strain rates have been obtained for a thin rotating disc having variable density using Seths transition theory. It has been observed that a disc whose density decreases radially, rotates at higher angular speed, thus increasing the possibility of a fracture at the bore, whereas for a disc whose density increases radially, recedes the possibility of a fracture. The deformation is significant for a disc having variable density and rotating at higher angular speed. "
