With compact tension specimen static stress analysis and fatigue life of crack as the research object, through the three-dimensional modeling software to establish compact tension specimen, using the finite element analysis software to sample statics analysis, get the maximum deformation and maximum stress, and the compact tensile samples prefabricated crack, using the fatigue crack propagation analysis software, The cycle times and a-N curves were obtained. This method can be used to calculate the fatigue crack propagation life and visualize the crack propagation process, which is convenient to analyze and master the fatigue mechanism.
