Abstract
Most structural failures are because of break in consisting materials. These breaks are initiated with
crack extension, which is a serious threat to the behavior of structure, so different methods have been
developed for distinguishing and showing such cracks. Meanwhile, the new methods based on
original wavelet transform are efficient and very important in the subject of signals. The main aim of
this paper is to fin the methods capable of distinguishing the specifications of cracks practically.
first a modal analysis of the structure was For this purpose, performed using ANSYS software, Then
the structure was analyzed as original wavelet using the wavelet toolbox of MATLAB software the
results are shown in two dimensional charts of coefficient-position.
