Sažetak
This article presents the results of a preliminary investigation of the existence of correlation between the experimentally determined cyclic parameters: cyclic strength coefficient , cyclic strain hardening exponent and cyclic yield stress and a number of monotonic properties such as: ultimate strength , yield stress and ratio, for a representative group of low-alloy steels. A very good correlation was established between the ultimate strength and the cyclic yield stress . Also, a good correlation was established between the cyclic strength coefficient and the combination of the ultimate strength and the ratio. No such correlation was found to exist between and any of mentioned monotonic parameters or their combinations for the group of low-alloy steels. These results were compared to those obtained for a group consisting of various steel types. The comparison confirmed the assumption that different steel groups should be considered separately when estimating cyclic parameters. Finally, a good agreement between the values of stress amplitudes calculated using the experimental and the estimated values of and shows that the cyclic parameters of low-alloy steels can be successfully estimated from their monotonic properties.
