    Crack initiation criteria for singular stress concentrations Part II: Stability of sharp and bi-material notches

  • Original language description

    The usual approach in assessing the stability of general singular stress concentrators developed and presented in the first part of this contribution is applied to configurations corresponding to bi-material notches. Two stability criteria based on the knowledge of the tangential stress and the strain energy density factor distribution in the vicinity of the bi-material notch are formulated. The critical stress for crack initiation and the initial crack propagation direction are calculated as a functionof the geometry and material properties of the bi-material notch.

    Kriteria iniciace trhlin z obecných singulárních koncentrátorů napětí Část II: stabilita ostrých a bi-materiálových V-vrubů

  • Czech description

    V práci jsou známé postupy lineární elastické lomové mechaniky rozšířeny a zobecněny také na další singulární koncentrátory napětí se singularitou různou od 1/2. Navržené postupy umožňují odhadnout počátek a podmínky pro šíření trhliny z obecného singulárního koncentrátoru napětí.
