Biologically Inspired Optimization of Functionally Graded Nickel-Alumina Composites

摘要

There has been a great deal of interest in optimizing the material distribution in materials using functionally graded materials concepts. Graded architectures can be used to tailor residual stress distribution in the film to enhance mechanical performance. Significant effort has been focused on the development of functionally graded nickel-alumina composites. A biological inspired optimization method, known as the Genetic Algorithm, is used to determine the optimal graded architecture for minimizing distortions in plates fabricated from these composites that are subjected to a thermal gradient.
