USING THE VIDEOEXTENSOMETRY AND UCI - HARDNESS FOR MONITORING OF AUTOMOTIVE STEEL SHEETS

The paper deals with examination of relation between the hardness and the size of plastic zone during the tensile loading. UCI (Ultrasonic Contact Impedance) micro-hardness method was used for hardness measurements. Deformation was evaluated by non-contact extensometry method – videoextensometry. Th...
