Out-of-Plane Elastic Waves in 2D Models of Solids: A Case Study for a Nonlocal Discretization Scheme with Reduced Numerical Dispersion

Figure 4

Dispersion curves for the Fourier-based approach. The curves displayed are plotted for equal to 1, 2, 5, and 10, as indicated. The gradual increase of quality is observed for the growing range of nonlocal interactions (increased value).
