Paper Title:
Characteristics of Electrical Discharge Pulse Sound for Hammering Test
  Abstract

In this study, the possibility of electrical discharge pulse sound for new inspection technologies instead of hammering test was investigated. Electrical discharge pulse sound was applied for hammering sound and sensor by using sound detection was applied for the optical fiber vibration sensor. Elastic wave was detected by optical fiber vibration sensor during electrical discharge. The plate thickness was changed from 0.5mm to 10mm. On the assumption that generation factor of elastic wave was only depending on a force, numerical analysis by using the finite element method (FEM) was adapted. The numerical analysis result using the FEM and the experimental result along with the electrical discharge were compared. The plate thickness was estimated by comparing with experimental signal and simulation one. It was found that plate thickness was able to estimate from comparing with experimental signal and simulation one. Moreover, a quasi-defect was created the plate by comparing with experimental results and simulation one. It was found that the defect shape was able to estimate by comparing with experimental results and simulation one.
