Fracture mechanics materials testing allows the determination of characteristic values which can be adapted to the behaviour of structures under real loading conditions, and it can ensure adequate safety with respect to the different possible modes of failure. Depending on the material behaviour, different fracture mechanics parameters can be used; the concept of crack resistance has been shown to provide a quantitative description of the fracture behaviour of ductile thermosets [1]. The critical crack initiation values determined on the basis of the various standards and drafts [2–6] are of special practical value.
