DESIGNING TO AVOID BRITTLE FRACTURE IN WELD METAL

FOR MANY YEARS WELD METALS FOR STRUCTURES DESIGNED TO AVOID BRITTLE FRACTURE HAVE BEEN CHOSEN ON THE BASIS OF WHAT NOW APPEAR TO BE RATHER ARBITRARY TESTS AND CONFLICTING REQUIREMENTS. THIS KNOWLEDGE HAS RESULTED FROM THE GRADUAL DEVELOPMENT OF FRACTURE MECHANICS WHICH NOW PROVIDE A SOUND BASIS FOR EXAMINING SOME OF THE ANOMALIES OF THE PAST. THIS ARTICLE IS BASED ON THE FIRST OF A SERIES OF RESEARCH MEMBERS' REPORTS THAT DESCRIBE AN EXTENSIVE INVESTIGATION OF WELD METALS BY MEANS OF GENERAL YIELDING FRACTURE MECHANICS. IT DEALS WITH THE EFFECT OF SPECIMEN SIZE, LOADING RATE AND NOTCH ACUITY ON THE RESISTANCE TO FRACTURE INITIATION OF A RANGE OF COMMERCIALLY AVAILABLE WELD METALS. /AUTHOR/
