1010 Steel, quasi-static tension stress-strain data =
Quasi-static tests were performed at ambient conditions on a MTS Servo hydraulic machine equipped with an 11 kip actuator. Load was measured with a load cell calibrated over an appropriate range. A slack adapter allowed the actuator to attain test speed before applying load to the specimen. Strain was measured using back-to back strain gauges bonded on the specimen Postyield strain was measured using a lightweight mechanical extensometer. Data from the extensometer and strain gauge were averaged to compensate for bending.

1010 Steel, compression stress-strain data
The material of specimens was AISI 1010. It was provided by industrial manufacturer as cold drawn cylindrical bar. The strain/stress relationship of AISI 1010 steelwas obtained by uniaxial compression test (see Fig. 3). In the large strain region of this material (ε > 0.64), the flowstress is assumed constant.

1010 Steel, torsion stress-strain data
Materials used in this study are two kinds of AISI 1010 steels (0.1 pct low-carbon steels) having a ferrite-pearlite structure. The chemical compositions are listed in Table I. They were fabricated in rods 120 mm in diameter; one was processed by converter steel making and hot rolling, while the other was processed by electric furnace steel making and hot rolling. For convenience, the former is referred to as A-Steel, and the latter B-Steel.
