摘要：
A formula is derived for determining the influence of temperature and loading rate on dynamic fracture toughness of a high-strength low-alloy steel (HQ785C) from thermal activation analysis of the experimental results of three-point bend specimens as well as by introducing an Arrhenius formula. It is shown that the results obtained by the given formula are in good agreement with the experimental ones in the thermal activation region. The present method is also valuable to describe the relationship between dynamic fracture toughness and temperature and loading rate of other high-strength low-alloy steels.
