High Performance and Optimum Design of Structures and Materials
Functionally graded materials (FGMs) possess properties that vary gradually and are highly heat resistant. When incorporating these FGMs into a structure, the required distribution of material properties must be determined and produced to specification. Thus far, an inverse analysis method has been used for estimating a distribution of a Young's modulus of FGMs. However, minimizing an objective function to estimate a material property using the Davidon-Fletcher-Powell method did not convergedoi:10.2495/hpsm140111 fatcat:4i4jzgllmbbvjhlqnom2lufqde
