Utilization of the high-speed cameras for monitoring deformation behaviour at the bending impact test

Popis výsledku v původním jazyce

Deformation characteristics of the materials used in the engineering industry are mostly determined at the common stress-temperature conditions (mostly loading rate 10 mm.min-1 and temperature 20°C). However in the operating life are materials loaded under conditions which are quite different from these standard conditions. Among such important operating conditions are e.g. operating temperature, state of stress and so on. Last but not least there is also the information about the tested material deformation behavior at the higher strain rates. This paper deals just with the influence of increased strain rate on the deformation distribution and magnitude. That is why there was chosen the bending impact test at the drop tower Instron CEAST 9350. As a tested material was used non-alloyed steel of the common quality acc. to ČSN 41 1373. The first aim of this paper was design of the testing jig. The second aim was subsequently effort to apply high-speed (HS) cameras PHOTRON SA3. For the own deformation computation and its distribution on the sample surface was used software ARAMIS 2M. At this point there was also effort to (by the optical measurement) determine the strain rate corresponding to the used impact velocity of the drop tower tool. So as a result there was not only the own testing jig for bending impact tests but also evolution and graphical illustration of the deformation distribution with the information about the strain rate magnitude. Subsequently from the measured results arise certain important recommendations for the future direction of such research.
