dcterms:description
Dvouparametrová lomová mechanika je aplikována na popis malých trhlin v blízkosti koncentrátoru napětí. Koncentrátorem napětí rozumíme singulární koncentrátor V-vrub nebo nesingulární U-vrub. V této práci je sledován jejich vliv na obecně orientovanou trhlinu. tato práce zkvalitní odhady únavové životnosti součástí s vruby. A two-parameter fracture mechanics method is applied to small cracks near a stress concentrator. The small crack in the present contribution is considered as crack influenced by the stress concentrator. The sharp V-noch or V-noch with radius $R$ are studieded here. The effect of V-notch geometry on the small crack fracture parameters is analysed. The necessary calculations are performed by using a finite element method (system Ansys). Obtained results are discussed from point of view of the small crack behavior. The small fatigue crack growth is especially influenced by the constraint level. The results improve the quality of fatigue life estimation of structure with concentrators.
