Mechanical properties

The group’s main activity is related to the topic of mechanical properties testing of materials, both in accordance with standards and non-standardized tests.

A large part of the conducted research concerns the determination of mechanical properties of modern materials available in small volumes using miniaturized samples (tensile tests, minidisks bending tests). The group also specializes in non-contact strain measurements using the digital image correlation method (DIC) on objects of various sizes (from microstructure elements to industrial facilities). In addition to issues related to testing mechanical properties of materials, the group also produces sinters by means of Pulse-Plasma Sintering (PPS) and works on the selection of materials for specific applications. Another area of our group’s activity is damage expertise of devices and construction elements.
