Sažetak
This paper presents the results obtained from the experimental study conducted in relation with the research focused to the plastic deformation development and its localisation during the static tensile test and test of the notch toughness on the welded steel sheets. The aim of experiments was to determine the possibilities of obtaining the data for the estimation of the welds toughness applying the video-extensometry scanning of the deformation distribution, to estimate deformations within the individual sections of the weld and to compare them with the notch toughness. Based of the results obtained it can qunatitied the relation between the strain and toughness of thich sheets.
