Abstract

Mechanical properties of ductile materials are very sensitive to environmental conditions in particular temperature. The paper shows the results obtained in the simultaneous testing of 5182 H111 Aluminium alloy, S275JR Carbon Steel and F114 Carbon Steel specimens using conventional methods and thermography. The infrared thermography was used to quantify deformation localization zones, also to relate the temperature changes of the specimens, continuously recorded by thermography, with the load extension diagram. It enables to predict reaching the critical stresses which cause the appearance of fractures and to define the criteria for determining the maximum sample temperature alteration in the field of elastic and elastic-plastic strains. Infrared thermography was found to be an efficient tool for investigating the deformation and damage scenario under tensile loading.
