dc.description.abstract | The effect of L-T and S-T orientations on FCGR is here in studied in 7050-T7451 and 2050-T8 aluminum alloys. The Low-cycle fatigue tests and hardness measurements have shown that specimen orientation has a minor effect on material plastic hardening. Lower FCG rates are obtained for both materials in the L-T orientation, which can be associated to the resistance at grain boundaries. The larger cyclic plastic zone attained in the L-T direction leads to an increase of the plasticity inducing crack closure. Crack deflection observed for L-T direction also affects the FCGR due to roughness inducing crack closure, longer crack path and lower effective ΔK. | pt_PT |
