Abstract

This chapter presents some of the aspects in the application of the finite element method (FEM) for structural health monitoring (SHM) problems. First, the procedure to select a proper FE mesh size for a given frequency content of a predefined input is given. A relationship between the damage size and the frequency of the predefined input signal is then established. Different methods of modeling flaws in FEM and their utility in SHM studies are explained through numerical examples. Limitations of FEM for SHM and possible remedies are also discussed.
