Abstract
During the last few years it has become more and more customary for major industries to use FEM simulations during the product creation process. Most of these metal-forming process simulations are based on elastic plastic behaviour of material and use non-deformable tools. For a correct use of FEM simulations in product development stages, it is very important to determine the accuracy of the simulations. For multi-stage processes, it can be more effective not to simulate the total process but only a few stages of the process, with the last stages usually being the most important ones. To start simulations half way the total process calls for information on the semi-finished product. This information is generated by means of measured values in order to decrease the total modeling time and to increase the accuracy. This paper shows a method developed for handling these problems. The method based on a fully automatic measuring device, including a LECO hardness tester. The results of these measurements were used to verify models, including models based on the transformation behaviour of strain-induced martensite. The examples presented are based on products made of a stainless steel called Nanoflex ™.
