EXTRAPOLATION DES SPANNUNGSINTENSITÄTSFAKTORS AUF GRUND EXPERIMENTELLER RESULTATE
Abstract
The stress intensity factor (SIF) is defined usually by following formulas for the fracture-modes l and II, respectively, with the full or half crack-Iength, α, the "far-field" stress σ₀ or τ₀ and a dimensionsless quantity k₁ and k₁₁ depending on the boundary conditions. It is shown, that the actual influence of the crack-length upon the SIF is diminishing with its growing value and in many cases the SIF depends practically on the far-field stress only. This makes an extrapolation method possible, which is checked by two photoelastic experiments.
