Abstract

Fatigue failure is one of the failure modes that commonly should be considered in machine component design. This study aims to estimate the fatigue stress concentration factor of 6061 aluminum alloy for a solid bar with various grooves numerically. A solid aluminum bar with a diameter of 8 mm and various groove radii between 1.00 mm to 8.00 mm was used during the simulation performed by commercial software. A completely rotating bending fatigue loading (R=-1) was carried out during simulation by applying various alternating stresses. The simulation results show that the fatigue stress concentration factor decreases as the ratio of groove radius to the bottom of the groove (r/d) increase. A decrease in the ratio of large bar diameter to small bar diameter (D/d) also causes a reduction in the fatigue stress concentration factor.
