Poisson's Ratio Extrapolation from Digital Image Correlation Experiments

Abstract

Digital image correlation, an optical method that uses speckle patterns to determine surface strains, has been used recently to investigate values for Poisson's ratio in solid propellant specimens. Work was performed on both a double-base and a composite propellant, and results indicate that the method is useful for determination of Poisson's ratio. Details of the experimental procedure, the advantages of the method over current approaches, and the results are described, as well as recommendations for future work.
