  • Numerical Simulation for Hammering Test Based on The FEMand The Adjoint Variable Method

抄録

<p>In this study, the identification of input signal at hammering test was carried out based on three-dimensional finite element and the adjoint variable methods. In the hammering test, the output signal measured by microphone and so on is only obtained, and the intensity of the input signal and the size and depth of defect, e.g. cavity and so on are not found. As the introduction for hammering test assisted system, numerical experiments for the identification of the input signal and position of cavity based on the three-dimensional finite element and the adjoint variable methods are shown in this study.</p>
