Abstract
Numerical simulations such as Finite Element (FE) modelling allow the simulation and prediction of guided wave propagation and scattering. Specific considerations concerning the choice of mesh, element type, time step, and analysis method are required to ensure stable and accurate simulations. Modeling considerations and validation against experimental results are shown for two examples of increasing complexity. The approximation of complex geometries and the effects on guided wave propagation are discussed. Examples concerning guided wave scattering at defects in single and multiple metallic layers of plate structures were compared against experimental results.
