Abstract:

Functionally gradient material components have better physical and chemical properties than homogeneous material components. Because of material distributing complexity and insufficient study on functionally gradient material, there are lots of difficult in analysis of functionally gradient material components. Theory of thermal properties of composites and finite element analysis software ADINA is used to analyze temperature field and stress field of gradient aluminum matrix composite piston reinforced by ceramic fibers which have different material composition functions.
