    Crack initiation criteria for singular stress concentrations Part I: A universal assessment of singular stress concentrations

  • Original language description

    In the contribution the limits of validity of standard crack linear elastic fracture mechanics are extended to problems connected with failure of structures caused by general non-crack-like singular stress concentrators. In the present part of the contribution a universal approach for assessment of general singular stress concentrators in terms of linear elastic fracture mechanics is formulated. The approach suggested in this part of the paper facilitates to answer the question whether in the vicinity of the stress concentrator a crack is created or not and what are the parameters controlling the crack initiation. The presented approach follows the basic idea of linear elastic fracture mechanics, i.e. the validity of small scale yielding conditions isassumed, and has a phenomenological character.

    Kriteria iniciace trhlin ze singulárních koncentrátorů napětí Část I: Univerzální přístup k hodnocení singulárních koncentrátorů napětí

  • Czech description

    V práci jsou známé postupy lineární elastické lomové mechaniky rozšířeny a zobecněny také na další singulární koncentrátory napětí se singularitou různou od ?. Navržené postupy umožňují odhadnout počátek a podmínky pro šíření trhliny z obecného singulárního koncentrátoru napětí.
