The issue of defect detection and diagnosis has gained wide spread industrial interest. Defect affects the industrial economic growth. Generally, defect in a structural element may occur due to normal operations, accidents, deterioration or severe natural events such as earth quake or storms. Defect can be analyzed through the method of measuring frequency, mode shape and structural damping. Our analysis has been made on the basis of non-destructive methods with the consideration of natural frequency. The study of cracks and its location is very important as the shaft is main parameter to transmit power from one point to another point in various industries. Failure of shaft is directly affects on the safety of environment around the machine. In this, study has been done on solid rotating shaft with slant crack. The analysis for cracked shaft is carried out by using experimental and simulation in FEA software. The experimental results are compared with ANSYS results.
