| Description
| - Tento článek je zaměřen na vliv velikosti a geometrie konstrukce na velikost a tvar lomové procesní zóny (LPZ) a následně také na průběh lomové energie disipované uvnitř LPZ během lomového procesu v konstrukcích vyrobených z kvazikřehkých materiálů. Vliv geometrie konstrukce na její lomové chování je zde popsáno pomocí dvouparametrové lomové mechaniky, konkrétně pomocí constraintu napětí u čela ekvivalentní elastické trhliny. Je zde dále rozvinut koncept lomové energie. Pozornost se zaměřuje na nalezení prostřední (mezilehlé) fáze lomu, kdy velikost a tvar LPZ (a současně také množství energie disipované uvnitř této zóny) není přímo ovlivňována volnými povrchy tělesa. Výzkum je prováděn prostřednictvím numerických simulací lomových testů ve dvou zkušebních konfiguracích vyznačujících se různými průběhy constraintu. Diskutovány jsou zde především vlastnosti průběhů lokální/průměrované lomové energie podél l (cs)
- This paper is focused on the influence of structural size and geometry on the size and shape of the fracture process zone (FPZ), and consequently on the progress of the fracture energy dissipated within the FPZ during the fracture process in structures made of quasi-brittle materials. The effect of structural geometry on its fracture behaviour is described here by two-parameter fracture mechanics, in particular by the constraint of stress near the equivalent elastic crack tip. The local fracture energy concept is evolved. Attention is paid to finding the intermediate stage of the fracture when there is no direct influence of the specimen boundary on the FPZ size and shape (and consequently the value of fracture energy dissipated within it). The research was conducted by means of numerical simulations of fracture tests in two testing configurations with different constraint conditions. The features of the distribution of local/averaged fracture energy along the specimen ligament are discussed. Based on
