Wide-Plate Crack-Arrest Testing: Evolution of Experimental Procedures

Source

Between September 1984 and December 1985, five wide-plate crack-arrest tests on A533B quenched and tempered steel were carried out on the 26-MN tensile capacity universal testing machine at the National Bureau of Standards. Each test was different with respect to the conditions of testing, specimen configuration, and instrumentation used to monitor the dynamic response of the specimen during crack propagation and subsequent arrest. The progressive changes in test procedure discussed here represent attempts to obtain desired crack-run and crack-arrest behavior and to improve the quality of the data collected. Also, the optimization of strain gage locations and the final choice of recording instrumentation are reported in detail. Two techniques for measuring crack velocity are compared. Efforts to cause crack initiation and propagation at lower values of stress-intensity factor than were found in the first test are also discussed.
