Influence of Testing Method on the Course of Anisotropy Coefficient

Popis výsledku v původním jazyce

The anisotropy coefficient rα [1] represents one of the main aspects of the materials deformation behavior, in addition to the basic material characteristics (such as e.g. yield strength, tensile ultimate strength, total ductility, uniform ductility). According to the standard, its value is calculated at a specific deformation value using the initial and actual measured length and width. However, modern materials testing methods offer the possibility to determinate its size throughout the deformation process that is however limited by the uniform ductility due to neck formation. In this paper, two such "modern" approaches are compared, where the values of anisotropy coefficient calculated according to the standard (i.e. just in one deformation value) are used as etalon. As these new testing methods, a mechanical strain gauge was used to determine the anisotropy coefficient throughout the whole static tensile test and optical contact-less deformation measurement system as well. Thus as the aim there was not only to measure and compare the anisotropy coefficient values courses during the static tensile test up to the uniform ductility, but also to compare them with the results measured by standard just in one deforma tion value. Possible utilization of these data can be found in the numerical simulation software.
