Presently, the need to characterize the constitutive parameters of materials has increased due to the manufacture of new materials and development of computational analysis software intending to reproduce the real behavior which depends on the quality of the models implemented and their material parameters.
Introduction The characterization of materials is having an increasing attention due to the manufacturing of new materials and development of computational analysis software.
However different materials may have similar properties.

Introduction The concept of functionally graded materials (FGMs) was first introduced in 1984 as ultrahigh-temperature resistant materials for aircraft, space vehicles and other engineering applications [1].
This is achieved by gradually varying the volume fraction of the constituent materials.
Material properties As mentioned above, functionally graded materials (FGMs) are non conventional composite materials, the mechanical properties of which vary continuously due to gradual change in the volume fraction of the constituent material.
