文摘Properties of wavelet of good localization were used to approximate displacement fields near the crack tip. Wavelet-numerical algorithm and simulation singularity problem of the crack tip,cere established. As an example, stress intensity factors were obtained. The numerical results show that this algorithm has good precision.
