Non-Destructive Inspection Using Magnetic Measurement and Application to Infrastructure Diagnosis

This year, Tokyo 2020 Olympics are going to be held, and new stadiums and roads have been constructed in the preparation. In contrast, the infrastructure facilities that were constructed during the economic growth—namely around the previous Tokyo Olympics in 1964—are turning 50 years old, and their aging is becoming a problem. The difficulty lies in the fact that the damage varies depending on the cases because every facility was custom-built and has been used in a different environment. Thus, accurate diagnosis of damage is crucial for efficient maintenance of the facilities that realizes both safety and long-life usage. As a method of non-destructive inspection, magnetic measurement has been explored because steel, which is a magnetic material, is used in most of the facilities. In this topical symposium, we invite five researchers engaged in non-destructive inspection using magnetic measurement. We look forward to your participation.

There is possibility of postponing this topical symposium because of COVID-19 outbreak.
In the case of postponement, the symposium booklet will be sent to annual subscribers after the original symposium date (May 15th).
