Steady thermal stresses in a plate of functionally gradient material with temperature-dependent properties.

Abstract

A functionally gradient material which decreases thermal stresses has been developed for structural components and/or mechanical elements in fields such as nuclear, aircraft and space engineering fields. Steady-state thermal stresses in a plate made of the functionally gradient material with temperature-dependent material properties are discussed. The main theme of this subject is how to distribute the components of the materials in the functionally gradient material to decrease thermal stress. The plate of an optimally functionally gradient material was determined to decrease the steady thermal stresses.
