Abstract

Ultrasonic guided waves are an attractive alternative to conventional methods because the elastic waves emitted at one location travel over along distance. By analyzing these waves, the presence of flaws may be detected. Mathematically, this is an inverse problem. A large varietyofmathematical methods to solve inverse problems consist in minimizing an instrumental objective function, which gives the difference betweenthe measured and calculated signals. Among these, the topological derivative describes the sensitivity of the objective function to infinitesimalinclusions on the material.
