dc.description.abstractThe main goal of this paper is the determination of the size and shape of the plastic zone in thin steel sheets. The aim of experiments was to analyze the influence of the material and type of the initial crack on the dimensions of the plastic zone. The plastic zone size and shape is also predicted by measuring hardness (HV 1) along and across the unbroken ligament. The hardness is measured by using UCI (Ultrasonic Contact Impedance) technique. The hardness values varied in dependence on the material and the initial crack. In this paper, the CT (Compact Tension) specimens of two steel grades with a notch and with an electrospark produced notch were used. Specimens were loaded by eccentric tension, whereby the deformation in the area around the notch was recorded by non-contact displacement measurement - a videoextensometry technique.en
