Influence of loading speed on yield strength value of S235 and C45 steels
Original language description
The aim of the paper is to evaluate the dependency of the yield strength of steels S235 and C45 on loading speed. In order to quantify this phenomenon, static and dynamical tension tests of both steels were realized and evaluated. Static tension tests realized on flat specimen confirmed values of yield strength under static loading given my material sheets of both steels. Dynamical testing has shown different behavior of steels under increased loading speeds. While the steel S235 has shown a significant growth of yield strength with the increased loading speed in the interval from 0 m/s till 3 m/s, the steel C45 has shown this ability in the interval from 0 m/s till 1 m/s only and the subsequent growth of yield strength has been very slow. In order to quantify the strain distribution in the specimen during dynamical tests using digital image correlation method, experiments were recorded using high-speed camera as well. Unfortunately, none of the results could be used since the colour applied on the surface of the specimen was eroded from the surface due to its fast deformation.
