Tension tests are carried out by using 9 types of specimens with circular or rectangular section at the parallel part, which are shaped by machine from 25mm thick plate of SS41 or SM50A. The test results are discussed to clarify any influence of the sectional configuration at the parallel part of the specimen on the stress-strain diagrams under mono-uniaxial tensile loading. Strain-hardening region on the stress-strain curve is fitted to each result by a modified Menegotto-Pinto Model. Two material constants including in this model are determined. These constants are compared with each specimen. Reduction of area and true stress at rupture are also compared. It can be concluded that the difference depending upon the sectional configuration at the parallel part is comparable to the error induced from the usual process at the experiment.
