Abstract

The aim of this paper is to analyse the influence of the loading rate in the range from 1 to 1000 mm/min, which corresponds to the tensile machine working range, on the strength properties and the formability characteristics obtained on standard and notched test bars made of steel strips. The combination of the loading rate and the test bar type made it possible to obtain the relationship of monitored variables in the strain rate interval from 10-4 to 10 s-1. In this interval, the strength properties of the tested strips thickness of 1, 1.5 and 1.8 mm increase exponentially, but formability does not change up to the strain rate of 1 s-1.
