Abstract
Evaluation of the dynamic elastic-plastic toughness properties of very tough structural steels is an expensive and complicated activity. For military purposes, the dynamic tear test and explosion bulge test have been used in the absence of a simple dynamic elastic-plastic toughness test. DREA has developed a simplified multiple specimen method of determining JId, which uses a standard drop, tower without instrumentation. A blunting resistance curve is generated, typically from blunting up to complete fracture, by impacting specimens using progressively larger weights and small changes in drop height. The lack of need for instrumentation puts the use of this test into the financial range of many more organisations. Specific test results will be given for HY 80 welds, prepared at DRA Dunfermline, tested at -5C.
