Abstract
Fatigue damage is the damage accumulation process under the repetitive cycle load, which is accompanied by degradation of material properties. It is great significant to study the fatigue life of aluminum alloy in the field of engineering application. The damage characteristics of 6061 aluminum alloy are studied by three-dimensional reconstruction and finite element method to estimate low-cycle fatigue damage based on the X-ray computer tomography. The results show that the estimated damage variables are accordant with those measured experimentally. Moreover, the three-dimensional reconstruction method combined with the finite element analysis method to calculate the material damage can meet the engineering requirements.
