Nondestructive Identification of Internal Crack Based on Wavelet A 6 ^.Lj ^TAV ^(jljjox ^ijJ^fa) T OJUJJ XV JJL> i^gJj oJ^JUb 4Jbte Analysis

Most of structural destructions take place because of components fracture. This event occurred by cracks that their development is considered as a serious threat for the treatment of structure. Therefore the exhibition and distinction methods of crack were the subject of wide verifications during last decade. Considering the local hardness differences arising from cracking and its effect on the treatment of structure, this article studies the distinction of internal crack in cantilever beam. Specimens were placed on harmonic analyses and the base of recorded reaction was analyzed by Wavelet transform. Also this text offers the sensitiveness of the above method due to the depth, angle and situation of crack, and possibility of its identification, in various conditions.
