Research summary
Study for maintenance and management of social infrastructure, and for disaster prevention Many social infrastructures exist in our country, and many of them are due for renewal in a number of decades. In view of the state of finance and shortage of manpower, maintaining and managing all these structures will prove to be very difficult. This is where non-destructive testing is drawing attention. Non-destructive testing (NDT) is a method to inspect for damages without damaging the structure. There are various NDT methods, and this study uses a method known as Acoustic Emission (AE). By applying the AE method onto various materials and components, the elucidation of their fracture mechanisms and the grasping of their soundness are evaluated. Furthermore, development of a “hybrid NDT method” will be conducted, using the merits, not only of AE, but of various other NDT methods.
