| Outline of Final Research Achievements |
We conducted research and development of the new method to improve inspection accuracy of the non-destructive inspection method for large scale concrete structure by using impact elastic wave method and Finite-difference time-domain method (FDTD method). In this research duration, we validate that the estimated wave propagation by FDTD method can improve inspection accuracy of our propose non-destructive inspection method. Moreover, we validate that FDTD method can estimate the sensor signal by our proposed non-destuructive inspection. Improvement of the further inspection accuracy can be expected by combining and using the estimated sensor signal and the measured sensor signal.
