Guided waves in anisotropic and quasi-isotropic aerospace composites: Three-dimensional simulation and experiment.

Highlights: [•] 3D guided wave propagation in composite laminates is simulated using elastodynamic finite integration technique. [•] Time domain and wavenumber domain comparisons are made between simulation, experimental data, and dispersion curves. [•] Results of comparisons match fairly closely and expected reasons for observed differences are discussed. [•] X-ray microfocus computed tomography data for a real composite delamination is incorporated into the simulation. [•] Results for delamination case demonstrate that complex geometry damage leads to unique scattering and mode conversion. [ABSTRACT FROM AUTHOR]
