Abstract

On the materials for car-bodies are posed quite tough requirements. As the most important of them there are tendencies to still lower car-body weight (to apply lightweight materials) as well as on the other hand also effort to improve its safety because of passengers. Quite a lot of material properties (e.g. Young´s modulus, yield strength, ultimate strength, ductility, etc.) enter into such effort. Last but not least there is also hardness that represents another very important material property. This paper deals with the measurement of hardness in dependence on deformation of tested materials. The major aim is from static tensile test to determine their deformation behavior (namely strain hardening exponent) and subsequently to measure surface hardness distribution as 3D color map surface. And finally to make conclusions from such results which arise from the experimental data especially in the area of non-uniform deformation (necking area).
