A NOVEL PROCEDURE FOR MEASURING THE IMPACT FRACTURE TOUGHNESS KId WITH PRECRACKED CHARPY SPECIMENS

摘要: A procedure is presented for determining the impact fracture toughness KId with precracked Charpy specimens without performing any load measurements. The KId-value obtained from preestablished response curves and a measurement of time-to-fracture. measuring technique fully dynamic does not impose restrictions on test conditions. applicability demonstrated by two different steels at temperatures.
