Opis

The growth of technology has placed rather severe demands on materials engineers to come up with novel materials at low cost to meet stringent and often contradictory property requirements which conventional materials cannot satisfy. In this respect,composite materials show great promise because of their superior stiness, high strength at elevated temperatures and better creep characteristics. Starting as early as 1906 the rotating isotropic disc has been studied by Grubler (1906)followed by Donatch (1912). Probably the first recognition given to the industrial importance of creep was by Dickenson in 1922. Experimental studies have demonstrated that steady state creep rate in aluminum or its alloys may be reduced by several orders of magnitude when it is reinforced with ceramic particles/whiskers like silicon carbide. The purpose of the present work is to study the isotropic and anisotropic properties with different distribution of material particulates. In many applications,rotating discs are exposed to elevated temperatures where creep deformation becomes important. From this point of view, an attempt has been made to analyze creep in rotating disc made of Al-SiC composites.
