Description
| - For analysis and technological process proposal of the forming operations is necessary knowledge about material deformation behavior. True stress value in the dependence on amount of the deformation is revealed by the stress-strain curves. These stress-strain curves represent one of the basic material characteristics and are simply determined by the static tensile test. By using standard measuring devices is this curve properly determined till the achievement utility deformation at the ultimate strength of the tested material. Disadvantage of such measuring approach rests in limited deformation range and the uni-axial stress state. However in the industrial praxis at car-body stampings production (e.g. in press shops) take more place multi-axial stress states. To improve accuracy of material deformation behavior at multi-axial stress state there is possible to use the Bulge test. By this experiment is material hardening process properly analyses up to the material failure. In this paper is evaluated stress state influence on the stress-strain curve of deep-drawing material. To measure required characteristic is firstly used common static tensile test equipped with conventional strain gauge. In the second case is for evaluation of static tensile test used contact-less optical device ARAMIS which enables to monitor deformation also in the area of necking after achieving ultimate strength. To observe stress state influence on material hardening is used the Bulge test with different tool geometry. Deformation distribution within the Bulge test is also analyzed by system ARAMIS. The experiment results are mutually compared and their utilization is mainly in the sheet forming analysis by FEA methods.
