Creep Transition in a Thin Rotating Dise Of Variable Density
AbstractCreep stress~s and strain rates have been obtained for a thin rotating disc having variable density using Sethrs transition theory. It h'11s been observed that a disc whose density decreases radially, rotates at higher angplar speed, thus increasing the possibility of a fracture at the bore, whereas for a disc whose density increaseslradially, recedes the possibility ofa fracture. The deforamation is signircant for a disc having variable denlsity and rotating at higher angular speed.
