  • Three dimensional cavity position and shape identification analysis based on hammering response waveform using the random tunneling algorithm

抄録

We present the position and shape identification analysis of a cavity using the displacement data assumed the hammering test. To solve the cavity identification problem, the adjoint variable and the finite element methods are employed. To obtain the optimal cavity position and shape, the random tunneling algorithm is applied. In this study, numerical experiment results focus on the accuracy of the identified position and the shape. According to numerical experiments, the accuracy of the identification result was improved by using the random tunneling algorithm.
