Abstract
An approach is proposed to evaluation of upper shelf impact toughness of Charpy sample depending upon degree of plastic pre-deformation of metal rolled stock. The derived analytical dependencies were analyzed, and main parameters were determined characterizing their change. A simple engineering dependence was proposed, which allowed evaluation of change of the upper shelf impact toughness of a Charpy sample depending upon degree of plastic deformation in fabrication and assembly of the metal structure elements
Keywords: welded joint, impact toughness, Charpy samples, tough fracture, deformation ageing, upper shelf, plastic deformation
