The influence of the local constraint in the near field zone of cracks in terms of the parameter σ m /σ v = f ( r, θ, s ) on fracture initiation and fracture resistance is investigated for several crack configurations in specimens and components. Experimental results from various authors are compared with corresponding numerical findings. Methods to transfer test results obtained for specimens to more complex situations in components are reported.
