| Abstract: | The novel identification method of single crack situated in a strip and parallel with the boundaries is studied. The relation between the parameters denoting crack and the reflection or transmission coefficient with an incident acoustic wave is first deduced. And then, the crack is identified by means of Genetic Algorithm (GA). The identification results indicate that GA has much higher identification accuracy. |
