| Abstract: | Slow dynamics that is introduced in this paper is one of new physical phenomena.It is well suited for monitoring in line production in structural components for the aerospace about detection of damage and progressive fatigue damage.We also introduce its background,the explanation of physical phenomena slow dynamics,the methods and devices for non-destructive detection of damage and some examples.Finally,it is provided some suggestions and the points of view about the application of slow dynamics,including the superiority and the shortage. |
