Influence of the dynamic loading on the mechanical properties of the ultra-high strength material

Popis výsledku v původním jazyce

The paper deals with analysis of the ultra-high strength steel at material tests under the high strain rates. In the experimental part was tested steel alloyed by manganese and boron with the predominant martensitic structure. This steel is used in the automotive industry for the car-body design where it is necessary to have parts which ensure the safety of passengers. To fulfill these required function is for these parts very important to know their deformation behavior under the dynamic loading (crash conditions) because it can vary in comparison with the low and uniform strain rates. Experiment was carried out in the drop tower Instron CEAST 9350 where it is possible to set the magnitude of the impact velocity. Moreover, high-speed cameras PHOTRON SA3 were also used to record the whole test. These cameras monitored the points displacement on the surface of testing sample which was loaded under the conditions of the uni-axial tensile stress state. For the own computation of the kinematics quantities there was used software PONTOS where the main goal was to determine the evolution of the given strain rate s (s-1). Moreover there was recorded the impact energy during the test by means of the force sensor under the different impact velocities.
