ABSTRACT
Most of the engineering or mechanical components that undergo fast wear and tear resemble the shape of a rotating disk, cylinder, or shell. This chapter helps the various researchers to know about the analysis of creep in cylinder and disk done by many authors. These two shapes have been actively studied by various researchers over the past years so that they can develop the materials which are stronger, stiffer, and are less prone to creep. A good amount of phenomenological study has been conducted in the field of creep analysis of rotating disks and rotating cylinders. Most of the researchers observed that monolithic materials such as aluminum and steel are not as strong as composite materials. In today’s time, scientists of material sciences are looking to create composites with more strength and having less impact of variation of temperature and pressure at a much less cost. This has led to a huge amount of research in functionally graded material that is designed for specific function and applications to show a graded variation in the materials properties, at an optimum cost. The properties of functionally graded material have been found to be more appealing than of conventional composites and are ideal for creation of future high speed space crafts which can withstand extreme temperature and pressure conditions of space tours. With the advent of nanotechnology, use of nanomaterials fast started picking up for making of engineering components from nanotech-based functionally graded materials. This chapter is split into two parts. The first section focuses on creep analysis in cylinder and the second part highlights the creep in disk conducted by various researchers during 1954 and 2020. The expressions of strains, stresses, and strain rates were calculated using constitutive equations, equilibrium equations, associated flow rule, yield criterion, and various assumptions.
