One of the most important input for the simulation software is the flow curve yield curve of the material. Although there are many tests which could be performed in order to construct the flow curve such as standard tensile test, hydraulic bulge test, frictionless dome test, etc., standard tensile test is the simplest and cheapest technique despite of its technical restrictions. In this article, the studies regarding to the creation of a specific MatLab code for processing of tensile test data are presented. This specific MatLab code is capable of determining the constants of Hollomon’s, Ludwig’s, Swift’s and Voce’s hardening equations with their regression results, as well. By means of this code, the proper flow curve of any material and also the Lankford parameters could be obtained and the hardening equations which fits best to the experimental data could be determined.
