Abstract
An evaluation of static crack resistance (K1c, 51c) of structural steels and their welded Joints is proposed, based on standard mechanical testing and impact toughness of Charpy samples, allowing for the dimensions of structural elements. The developed approach allows for the difference in the deformation gradients in the tip of a crack-like defect and notch of a Charpy sample, which results in that the structural parameters, responsible for fracture initiation, are under different loading conditions depending on their dimensions.
Keywords: crack resistance, structural steels, welded joints, impact toughness, tough fracture, critical deformation, structural elements
