Steel Mechanical Properties at Different Strain Rates

Abstract

Dynamic test results reported by different investigators on structural steel, deformed reinforcing bars, and deformed wires subjected to monotonic tension are used for deriving empirical expressions for the ratios of static to dynamic values of the yield and ultimate stresses, yield and ultimate strains, and the strain at the end of the yield plateau. The principal variables in the expressions are the rate of straining and the steel static yield strength. These expressions are then used for developing dynamic constitutive models for monotonically loaded steel.
