摘要

In order to derive a method for estimating the strength coefficient and strain hardening exponent of steel, the performance parameters of 86 kinds of steel taken from American Iron and Steel Institute (AISI) Bar Steel Fatigue Database were examined and equations that related the strength coefficient and strain hardening exponent to the ultimate tensile strength and yield strength were developed. Correlations from the literature among the strength coefficient, strain hardening exponent and other monotonic tensile properties were also examined and compared to the relationships proposed in this study using the data of 86 kinds of steel. The proposed method was shown to be better used to estimate the strength coefficient and strain hardening exponent.
