Optimization study of ballistic impact tests on carbon–carbon composites

Abstract

In this study it is intended to optimize a high velocity impact case of a composite plate. The case is selected from the literature based on its dataset properties (e.g. amount of inputs and outputs, number of tests, physical relations with real life situations and relations between the properties studied on). The base study focused on failure response of advanced carbon-carbon composites under high velocity impacts. In the present study, two unique models are introduced within the scope of the present study as dimensionless damage areas of front and back sides of the composite plate. Multiple nonlinear regression method is used for objective functions of the optimization problem. The prediction models found in the present study are in first order trigonometric multiple nonlinear regression form; thus, these models can be considered as the basic prediction functions of high velocity impact response of carboncarbon composites under high temperatures, in processing power terms. Since the determination coefficient values have been found quite similar with the ones in the base study, the presented models in this study can be considered successful to predict the results.
