電磁非破壊検査及びその支援磁場解析技術

抄録

A nondestructive inspection method using magnetic information is described. In this method, the defect shape is restored by the inverse analysis from the leakage magnetic flux density distribution. Furthermore, enrichment functions are created using conformal mapping. Defects of complicated shape are modeled by extended finite element method using these enrichment functions, without depending on mesh division.
