Abstract: [cze] [eng]
V rámci dvouparametrové lomové mechaniky je studován vliv nehomogenity na chování krátkých trhlin. V závislosti na materiálových vlastnostech jsou stanoveny hodnoty součinitele intenzity napětí, T-napětí a hustoty deformační energie. Hodnoty daným lomově mechanických veličin jsou stanoveny užitím konečných prvků (ANSYS). In case of two-parameter linear fracture mechanics a study of inhomogeneity influence on behaviour of short cracks is performed. The values of stress intensity factor (KI), T-stress and strain energy density (SED) are shown as a function of material constants of both components. The calculation of numerical values of mechanical parameters is accomplished by using finite element method ANSYS.
Keywords: bi-material iterface; short cracks; stress intensity factor; T-stress
