An adaptive frequency domain finite element model for surface wave testing of pavements
The proposed adaptive FE model makes it possible to simulate wave propagation in a pavement structure over a wide frequency range using a normal size computer. The geometry and mesh size are optimized and regenerated for each frequency using a simple script in the commercial FE software package. Results from the FE model agree well with normal mode dispersion curves for a 3-layer reference pavement model. The proposed approach is fast and computationally efficient enough to be used as a forward model for iterative surface wave inversion. By solving the model in space-frequency domain it is also straight forward to implement frequency dependent material properties as well as properties varying in any direction of space, even within a layer.
