Property Estimation in FGM Plates Subject to Low-Velocity Impact Loading
A property estimation sequence is presented for determining local elastic properties of a two-phased, two-constituent functionally graded material (FGM) plate subject to impact loading. The property estimation sequence combines the use of experimentally determined strain histories, finite element simulations of the experimental impact events, and an analytical model of the impact tests. The experimental, computational, and analytical models are incorporated into a parameter estimation framework, based on optimization theory, to solve for material properties of individual graded layers in the FGM plate specimens.
