概要
A new inspection technique using AE (acoustic emission) sensor has been developed for the purpose of evaluating the integrity of steel rods and pipes, and sensitivity analyses were made for degradations of steel rods and pipes from a theoretical viewpoint. Inner surface corrosion model of the piping changing the corrosion contents were simulated frequency distribution by dynamic analysis using the finite element method, and comparisons with experimental results obtained from mockups with simulated degradations were reported.
