dc.description.abstract | This work focuses in the analysis of mixed-mode crack propagation and fatigue of two dimensional rotating blades using the Extended Finite Element Method (XFEM). A horizontal plate model simulates a UH-60 helicopter rotor blade rotating at a constant angular velocity. The calculation of body forces mixed-mode fatigue analysis was implemented into XFEM. The critical location is at about 8% from the rotating hub for a single-edged crack. At this critical location, a crack size of approximate 15% of total blade width will cause catastrophic failure. | en_US |
dc.description.abstract | Este trabajo se enfoca en el análisis de la propagación de grietas y fatiga en modo mixto de placas rotando en dos dimensiones usando método extendido de elementos finitos (XFEM). Un modelo de placa horizontal simula al helicóptero UH-60, girando a una velocidad angular constante. Se ha implementado en XFEM la calculación de las fuerzas de cuerpo y el análisis de modo mixto de fátiga. El lugar crítico se encuentra en alrededor del 8% con respecto al centro de rotación. En esta localización crítica, una grita del 15% del ancho de la aspa produce falla catastrófica. | en_US |
