Abstract

A STUDY ON STRESS ANALYSIS OF FGM STRUCTURES

Abhilash Kumar Sinha* and Dr. H.P. Singh

ABSTRACT

An FGM typically consists of a composite material with a spatially varying microstructure designed to optimize performance through the corresponding property distribution. Property distributions are found in a variety of common products that must have multiple functions (i.e., multifunctional), such as gears, which must be tough enough inside to withstand the fracture, but must also be hard enough on the outside to prevent wear. Gear teeth are in constant contact, and therefore their surface hardness becomes of primary concern to prevent them from deteriorating during use. However, if this factor were the only considered design criterion, the gear may suffer from fracture under the constant loading since hardness and toughness are mutually exclusive. Similarly, a turbine blade also possesses a property distribution. Again, the blade must be tough to withstand the loading it is subjected to, but it must also have a high melting point to be able to withstand high temperatures on the outer surface. As with hardness and toughness, these different material properties tend to mutually exclude one another.
