Present work gives an overview of cracks determination in material usingnatural frequency and wavelettransformation method and its application tocurrent engineering problems. In this technique, comparisonbetween actualnatural frequency (without crack) and frequency due to crack propagation ismade using EulerBeam theory. When cracks are present in structure, natural frequency of material deviates from its originalfrequencyandresultdifference will measure in term of crack. Whole analysis procedure starting frommodeling, meshing and resul tinterpretation done on well-known numerical tool ANSYS. The main aim ofproposed study is to detect critical areas especially crack initiativezone before doing actual fabrication ofcomponents and avoid the breakage of it. Effects of a breathing crack on thevibratory characteristics of arotating propeller shaft are investigated. Here three types of load consideration have taken such as axial,bending and torsionloadings. Results of numerical Finite Element Method (FEM) arevalidatedusingnumericalresultshasdoneusing MATLAB.
