Original abstract
The methodology of fatigue crack growth simulation based on the calculation of stress intensity factor function from finite element results, subsequent crack growth analysis performed in NASGRO and application on integrally stiffened wing panels are described. Large experimental program comprising both the constant amplitude and spectrum tests on integral panels and CCT specimens was undertaken in order to enable verification of simulations.
Czech abstract
Je popsána metodika simulace šíření únavové trhliny v integrálním vyztuženém panelu křídla zahrnující použití MKP pro stanovení faktoru intenzity napětí a navazující výpočet růstové křivky trhliny pomocí programu NASGRO. Pro verifikaci výpočtů byly uskutečněny únavové zkoušky integrálních panelů a CCT vzorků.
