STRUCTURAL IMPLICATIONS OF FRACTURE TESTS ON A1 STEEL

RESULTS OBTAINED IN TESTS ON NOTCHED TENSION BARS ARE REVIEWED AND THEIR SIGNIFICANCE IN THE DESIGN AND BEHAVIOR OF CIVIL ENGINEERING STRUCTURES IS CONSIDERED. BOTH STRAIN RATE AND TEMPERATURE ARE EMPHASIZED AS IMPORTANT ENVIRONMENTAL PARAMETERS. SERVICE STRAIN RATES ARE REPORTED FOR A NUMBER OF STRUCTURES. IT IS SUGGESTED THAT ACCEPTANCE TESTS BE CARRIED OUT AT AN APPROPRIATE STRAIN RATE AS WELL AS TEMPERATURE FOR THE PARTICULAR STRUCTURE IN VIEW. VARIOUS TRANSITION TEMPERATURES ARE CONSIDERED. THE TRANSITION OF GREATEST PRACTICAL SIGNIFICANCE APPEARS TO BE THAT FROM LOCAL YIELD AND FRACTURE TO GENERAL YIELD. HIGH NOMINAL STRESS LEVELS MAY BE NECESSARY FOR BRITTLE FRACTURE. THESE MAY RESULT FROM THE PRESENCE OF SECONDARY STRESSES, STRESS CONCENTRATIONS, RESIDUAL STRESS AND IMPACT. /AUTHOR/
