Estimation of the cyclic shear stress‐strain curve from tensile properties for steels

Abstract

The objective of this study is to derive a method for estimating the cyclic shear deformation properties (the cyclic shear strength coefficient and cyclic shear strain hardening exponent) of steels from common tensile properties. For this purpose, equations that relate the cyclic shear strength coefficient and cyclic shear strain hardening exponent to the monotonic tensile properties (the ultimate tensile strength and monotonic yield strength) are established on the basis of the 15 kinds of steel taken from the technical literature. Validity of some of the more commonly used methods of estimating cyclic shear deformation properties is examined and compared to the correlations proposed in this study. The proposed method is shown to be better used to estimate the cyclic shear deformation properties.
