Emphasis is normally on the detection of defects in materials.
The focus of this study is to analyze Acoustic Harmonic Generation phenomenon by Finite Element Analysis. Three different cases have been analyzed and compared with experimental and theoretical data. Technique of Finite Element Analysis becomes important from the fact that once it is validated, it can be used to obtain insight into various practical conditions without the need for expensive experiments. Acoustic Harmonic Generation may be used for the detection of closed cracks and kissing bonds, which are not easy to detect by normal ultrasonic techniques. This technique can also be used in determining the bond strength at the diffusion bonds.
