The objectives of this paper are to evaluate the factors affecting the fatigue crack propagation(FCP) behavior in AZ31 magnesium alloy. FCP experiments have been performed on the specimens of AZ31 magnesium alloy under various conditions such as a loading frequency, a specimen thickness, a maximum fatigue load, and a load ratio and the obtained results were analyzed to find the influence factors on the FCP behavior in magnesium alloy. It is necessary to consider the influence factors for the design and the maintenance of lightweight structures. The correlation between the crack growth rate exponent and the crack growth rate coefficient, which are FCP behavior parameters, was also analyzed and the regression model was presented.
