Abstract

In certain fracture problems, time becomes an important variable. In general terms, one can say that an increase in loading rate decreases fracture toughness when brittle behaviour prevails, while crack resistance is improved in case of fully ductile behaviour. This paper provides an overview of the currently available experimental and analytical methodologies (in most cases not covered by official test standards) for characterising the fracture toughness of a steel under elevated loading rates.
