DYNAMIC FRACTURE TOUGHNESS TESTS ON A302-B STEEL

Using dynamic loading, fracture toughness tests were made on annealed, and normalized and tempered A302-B steel at temperatures from minus 320 to 125 Fahrenheit. Fatigue precracked compact tension specimens were used. The specimens were separated into two groups with one group fatigue precracked under a higher load level than the other. Higher fracture toughness values were obtained for the specimens precracked at the higher load. Dynamic K sub Ic values determined in this investigation were lower than static K sub Ic values for the same materials as reported earlier by another investigator.
