Dynamic fracture toughness determination using precracked Charpy specimens

Dynamic fracture of high-strength metallic alloys: experiments and modelling

“…(Viehrig et al, 2002) linked the Master Curve concept and Charpy impact test to determine dynamic fracture mechanical parameters of a nuclear reactor pressure vessel steel. (Shuter, 2002) studied the dynamic fracture behaviour of a low alloy pressure vessel steel measuring the load-time data by two different methods: a piezoelectric Dynamic Fracture of High-Strength Metallic Alloys: Experiments and Modelling 14 force transducer mounted on the specimen striker and strain gauges on the specimen surface near the crack tip. It was found that at higher velocities the transducer was affected by the inertia of the specimen.…”

“…Representative examples of this particular methodology can be found in (Anderson and Rosakis, 2005;Joudon et al, 2014;Kalthoff, 1985;Rubio-González et al, 2008;Shuter, 2002;Xu et al, 2012;Yokoyama, 1993) Purely optical methods are also very extended since, in general, they are inertia free. The shadow optical method of caustics (Kalthoff, 1986;Manogg, 1964) was the first successful optical method.…”
