Summary:The invention relates to a finite element analysis method for crack propagation, in particular to a numerical value analysis method using wavelet extension as a new finite analysis unit. The method comprises the following steps that: based on a computer-aided drawing software, a gear meshing model containing any crack failure is built; the module is imported into a finite element analysis software ABAQUS, and geometric data of a finite element mesh is obtained by combination of ABAQUS meshing and data output functions; according to the obtained data, a mathematics-assisted calculation software is applied to a program to calculate the element stiffness matrix of a wavelet extension unit, and then according to the mesh of the analyzed structure, the overall stiffness matrix of an integratedstructure is arranged; and after boundary constraint conditions and loads are introduced, a finite element equation is solved to obtain the numerical value solution of crack propagation. In the invention, the growth condition
