Some Comments on Dynamic Crack Propagation in a High-Strength Steel

Source

The dependence of the dynamic plane-strain fracture toughness, KId, on crack velocity was measured for propagating cracks in SAE4340 steel at room temperature. It has been shown that KId for SAE4340 steel in the quenched-and-tempered condition increases slowly for increasing crack velocity up to ˙a ≈ 100 m/s and then increases sharply above 100 MNm−3/2 at ˙a > 1000 m/s.
