The determination of constitutive relation from the miniature tensile test is of high interest in multiple areas. Here, a convenient experimental method is proposed to determine the true stress–strain curve from the miniature tensile test. The instantaneous cross-sectional area is estimated by only one camera in aid of digital image correlation technique. This method was applied on commercial pure titanium and aluminum 6061 alloys, and the results indicate that the extracted true stress–strain curves are not scale-dependent. The derived mechanical properties from miniature specimens match well with the results of standard specimens. The correctness of the true stress–strain curve was evaluated by the finite element analysis method. The results suggest that the derived true stress–strain curve is capable to represent the constitutive behavior of the tested materials.

To solve the true stress strain of Cr8 steel, a method of cone inversion is used to deal with the high temperature tensile data. Based on the precise determination and description of sample size, the test data is analyzed in the SSC(Stress strain calculator) software developed on MATLAB, and the true stress strain curve of Cr8 is drew. The true stress strain curve calculated by this method is smooth and continuous, and more identical to the principle of metal elastic-plastic deformation process, which shows a good promotion value.

Abstract Various mechanical models explaining the plastic deformation of metals have been proposed. One of the present authors has shown that in some cases an analytical expression for the stress-strain curve and the hysteresis curve of a metal in the plastic range can be deduced from such a model. The present investigation is a further analysis of the model leading to the computation of the change in potential energy of the metal due to work-hardening.
