“…effects which are due to variations in the plan view dimensions of a specimen) can easily be studied on thin‐walled specimens with a constant thickness, and a width much greater than the thickness, as no out‐of‐plane constraint effects disturb the interpretation. This is why this kind of specimen, the global behaviour of which can be characterized by plane stress, has been extensively studied [ 18–21].…”

Crack growth resistance can be substantially affected by the constraint conditions of a structural member which in turn are mainly a function of geometrical variables and the degree of plasticity. Standardized test methods are restricted to high constraint conditions as represented by deeply cracked bend‐type specimens and may hence lead to conservative structural assessments. It is demonstrated that adjusted testing can be used to reduce the degree of conservatism. Due to rapidly increasing computer capabilities, a combination of conventional R‐curve testing with micromechanical models emerges as an accurate tool which may permit routine evaluations of practical situations in the near future.

“…This is the reason why these materials in general exhibit high values of fracture toughness as well as good crack growth resistance, see e.g. Schwalbe et al [25]. The question arises, how phase transformation influences the fracture properties and how the formed martensite fails, which is typically assumed to be hard and brittle.…”
