K-2326 電気ポテンシャル法を用いた複合材料ボルト継手の損傷検出(J03-5 ひずみ計測)(J03 知的材料・構造システム)

In order to assess the structural integrity of bolted joints of composite structures, it is necessary to detect damage caused by bearing load. By using conventional monitoring methods, it is difficult to detect the damage. For the purpose to detect the damage of bolted joints, a damage detection method using the electric potential method was experimentally investigated. As a result, it is shown that the damage of bolted joints of composite structures can be detected by the method.
