EFFECT OF LOADING RATE ON THE FRACTURE TOUGHNESS OF SEVERAL HIGH-STRENGTH STEELS

Simple techniques are described which enable plane strain fracture toughness (K sub Ic) values over a wide range of loading rates to be determined. Difficulties in interpretation of load-time curves at high loading rates due to inertial loading effects are discussed. The K sub Ic values plotted as a function of the stress intensity rate, K, reveal considerable variation between different steels and it is shown that the influence of loading rate on fracture toughness of high-strength martensitic steels is not as simple as hitherto been supposed.
