In contrast to strength calculation the fracture mechanics assumes the existence of cracks which might further propagate due to the operational load. First, the present paper illustrates the general procedure of a fracture mechanical evaluation of fatigue cracks in order to assess practical damage cases. Fracture mechanical fundamentals which are essential for the calculation of the stress intensity factors <jats:italic>K</jats:italic> <jats:sub>I</jats:sub> and the experimental determination of fracture mechanical material parameters (e.g. threshold Δ<jats:italic>K</jats:italic> <jats:sub>I,th</jats:sub> against fatigue crack growth, crack growth rate curve) are explained in detail. The subsequent fracture mechanical evaluation on the basis of the local stress situation at the crack tip and the fracture mechanical material data is executed for different materials and selected crack problems. Hereby, the main focus is on the material HCT590X as it is the essential material being investigated by TRR285.</jats:p> Walter de Gruyter GmbH2022 eng Mechanical EngineeringMechanics of MaterialsGeneral Materials Science 0025-5300 2195-857210.1515/mt-2022-0191 64101437-1449 B.
