Abstract
Consideration is given to the principles of operation and software of the optical and optical television imaging systems designed for detailed quantitative investigations of the processes of plastic flow and fracture occurring in metals and alloys. The data on the systems' resolution, accuracy of measurement and response are reported. The potentialities of the experimental techniques developed have been evaluated and used to advantage for investigating plastic flow localization with the aid of double-exposure speckle photography and special-purpose circuit designs, which make use of decorrelation of two different speckle patterns of the deforming solid's surface. The attractiveness of the effort is illustrated by the data on the kinetics of the process of plastic form changing obtained by the above techniques.
