Read how the EduDIC is used by Esslingen University of Applied Sciences to investigate sheet metal forming processes in corporation with Mercedes-Benz AG and Autoform.
In 2021, the Laboratory for Forming Technology and Laser Material Processing (UTL) of the Faculty of Machinery and Systems at the Esslingen University of Applied Sciences (Hochschule Esslingen) in Germany, acquired a Digital Image Correlation (DIC) system from Limess Messtechnik & Software GmbH, a distributor of Dantec Dynamics. The EduDIC system is being used for optical measurements of multi-axial strain for applications in the field of metal forming, as part of a development project in a corporation with Mercedes-Benz AG and a software simulation company, AutoForm. The system is also being used for the tuition of engineering students and further research in materials testing.
The advantage of using EduDIC is that it is the only technique that can be used for the measurement of full-field strain. When performing sheet metal forming tests it is very important to record the failure point of sheet metal materials under multiaxial strain. In the case of complex-shaped sheet metal parts, there is a different strain condition at every point, which cannot be represented by performing classic tensile testing. In addition, the measurement cannot be performed using mechanical extensometers either. As such, DIC is an ideal measurement technique that spatially resolves strain and provides clear measurement data.
