Abstract
The fatigue life of AISI 4140 steel under certain conditions using alternating stress in specimen standard in the fatigue test of flexion rotation type was studied. The finite element method (FEM) was applied by commercial software ANSYS quantification of fatigue damage in this material. The effect of roughness, machining, polishing and annealing was evaluated in the generation of fatigue damage. The results obtained by experimental, analytical and numerical method was compared. The rule linear Palmgren-Miner applied was adequate in predicting the fatigue failure when applied to the experimental results. This Palmgren-Miner model can be applied for control tools process production mechanical components metallic used and improvement industry metal mechanical using in CAD simulation.
