Daftar Isi: ESTIMATION OF CREEP PARAMETERS IN AN ISOTROPIC UNIFORM COMPOSITE CYLINDER

Daftar Isi:

In applications such as pressure vessel for industr ial gases or a media transportation of high- pressurized fluids and piping of nuclear reactors,the cylinder has to operate under severe mechanical and thermal loads,causing significant c reep hence reduced service life (Gupta and Phatak,2001;Tachibana and Iyoku,2004;Hagihara a nd Miyazaki,2008). As an example,in the high temperature engineering test reactor,the temp erature reaches of the order of 900 oC (Tachibana and Iyoku,2004). The piping of reactor cooling system are subjected to high temperature and pressure and may be damaged due to high heat generated from the reactor core (Hagihara and Miyazaki,2008). A number of studies pertaining to creep behaviour of the cylinder assume the cylinder to be made of monolith ic material. However,under severe thermo mechanical loads cylinder made of monolithic materi als may not perform well. The weight reduction achieved in engineering components,resul ting from the use of aluminum/aluminum base alloys,is expected to save power and fuel due to a reduction in the payload of dynamic systems. https://www.ijiert.org/paper-details?paper_id=140253
