“…The fixture essentially provides a boundary condition for the specimen plates very close to the actual tests (despite the fact the fixture was shown to configure the plate specimens as circular plates with simply supported boundary conditions [Larson 2008]). The specific details surrounding the plate fixture can be found in [Larson 2008;2009]. The fixture and attachment screws were composed of 18-8 grade stainless steel and were assigned properties (1) elastic modulus, E = 193 GPa; (2) Poisson ratio, = 0.290; and (3) density, = 8030 kg/m 3 .…”

“…Banks-Sills et al [2002] also studied an FGM system under dynamic pressures of various temporal application. Larson et al [2009] performed impact tests on titanium-titanium boride monolithic and functionally graded specimens and further developed finite element simulations that approximated the impact tests with a strong degree of correlation. With the exception of the last reference, all of these works were performed using analytical and computational techniques, but none of them were compared to physical or experimental data given the fact that very little test data of any kind associated with functionally graded composites can be found in the literature.…”

A property estimation sequence is presented for determining local elastic properties of a two-phased, twoconstituent 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. The property estimation sequence was demonstrated using impact tests performed on a titanium-titanium boride (Ti-TiB) FGM plate system. The estimated material properties of the Ti-TiB FGM from the sequence were shown to correlate well with published material properties for the titaniumtitanium boride FGM system. The estimated properties were further input into a finite element model of the impact events and were shown to approximate the experimental strain histories well. This property estimation framework is formulated to apply to virtually any two-phase FGM system and is thus an invaluable tool for research engineers studying the response of FGMs under load.

“…It uses energy-balance models to assess the strength and the contact time. Many authors are interested in the study of the behavior of structures subjected to impact loads [2][3][4][5][6]. Larson et al [5,6] developed a combined analytical and experimental methods to study the behavior of a Functionnally graded circular plate under different boundary conditions.…”
