Study of mechanical behaviuor for DC05 steel using tensile test

Abstract

A study about this material has been done in order to find its characteristics. First, tensile tests have been done for the main parameters, like the Young modulus. Then, tensile tests with specific captors have been done in order to find the Poisson parameter. The following parameters, which were found, will be used in order to identify the mechanical behaviour of the material: Young modulus, Poisson coefficient, elastic limit, fracture limit, true strain/true stress curves. The considered thickness of the material is 1mm. From the true strain/true stress curves, only the plastic zone will be used in order to identify the elasto-plactic behaviour of the material. In fact, the Young modulus and the elastic limit are enough to have the elastic zone, of the true strain/true stress curve, in the element finite simulation. A power law, with A and m identified parameters is used to describe the plasticity of the DC05 material.
