An adaptive frequency domain finite element model for surface wave testing of pavements

In English

Författare

Summary, in English

The proposed adaptive frequency domain finite element (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 a 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 and intended to be used as a forward model for iterative surface wave inversion.
