Application of IR Thermography for Determination of Material Properties

The paper presents the results of experimental research in which the flat specimens have been tested under tensile loading. The specimens are made of nodular cast iron. The experiments are performed under two different deformation rates using standard specimens. Displacement and temperature distribution on the surfaces of the specimens, during experiment, are determined using the optical measuring system ARAMIS 4M (digital image correlation system), thermocouples and infrared thermography. The goal of the research was to find correlation between the elastic deformations and increase of the surface temperatures.
