Executive Summary

There are several techniques of non-destructive damage detection in structures. However, these techniques are expensive and require an accurate examination of large extension of the structure under analysis. The numerical techniques can be helpful for non-destructive examination of structures. Such techniques may show a possible location of damage and thus decrease substantially the area to be examined and, consequently, may turn the non-destructive tests less expensive. Among many numerical methods, the boundary element method presents positive attributes that can be used in formulations proposed to solve the problem of detecting damages in structures such as beams.
