Applying self-developed test set-ups and experimental mechanics, we are capable of determining the material properties of samples with at least one dimension in the microscale. The testing of micro-parts is a routine, everyday occurrence for us, and we also carefully prepare small samples from larger components in order to determine the local material characteristics of critical parts. Our aim is to contribute to current material models, the design of metamaterials, the optimization of local materials properties and the understanding of size effects, which frequently appear in micro-regime samples.

Mechanical testing of micro-samples
Special test set-ups are used in order to determine the properties of very small material samples. For example, the fatigue characteristics of 200 µm cantilevers were tested, the samples coming from electrical steel sheets that typically find application in the automotive sector. From mechanical construction, to the control and DAQ systems, the test set-ups are constantly being further developed. The set-ups are used in order to determine ...
