04.1 - Material Issues, Fatigue and Damage ToleranceCRACK PROPAGATION STARTING AT HOLE’S EDGE GROWING TO PLATE’S MAJOR DIMENSION USING FEMB.L. Nolli¹, A.T.A. Melo¹, C.A. Cimini Jr.¹; ¹UFMG, Brazil Holes edges are the preferential way for fatigue crack nucleation. NASGRO software don’t predict the crack propagation if the dimension between the edge and the center of hole is bigger than half of total width for a crack on full plate thickness that starts on hole. This paper’s objective was to develop a FEM to evaluate the stress intensity factor (K) for this scenario. |
