Estimation of critical values for crack propagation from sharp v-notch
Original language description
The aim of this paper is to investigate the beginnings of crack propagation from sharp V-notches. Stress distribution around the tip of a V-notch is described on the basis of linear-elastic fracture mechanics. The V-notch is a singular stress concentrator with a singularity exponent dependent on the V-notch opening angle. The stability criteria are generalized for a stress singularity different from 0,5. Using FEM analysis the critical stress for crack initiation was estimated as a function of the V-notch angle. The results of numerical calculations were compared with experiments taken from the literature.

Stanovení kritické hodnoty pro šíření trhliny z ostrého v-vrubu
Czech description
Cílem tohoto článku je prozkoumat rozdělení napětí u čela V-vrubu. V-vrub je obecný singulární koncentrátor napětí s exponentem singularity závislým na úhlu otevření vrubu. Klasická kritéria stability jsou odvozena pro exponent singularity 0,5. Pomocí konečnoprvkové analýzy je zjistěna funkční závislost kritické hodnoty napětí na úhlu rozevření V-vrubu.
