A new procedure was developed in order to estimate the stress intensity factor for impact fracture toughness tests. The dynamic stress intensity factor is evaluated from the static stress intensity factor and the impact response function as a correction factor for inertia effect. The impact response

For the application of the weight function method the crack opening displacements for a reference case have to be known. An approximate method to derive the crack opening field from the stress intensity factor was proposed by Petroski and Achenbach [Engng Fracture Me&. 10,257 (1978)J. The limited ac
