摘要
利用小波具有的良好局部化特性 ,用小波函数对位移场进行逼近 ,建立了小波数值计算格式 ,模拟了裂纹尖端的奇异性问题· 算例求出了裂纹尖端的应力强度因子 。
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 were established. As an example, stress intensity factors were obtained. The numerical results show that this algorithm has good precision.
