Description

Compute guided elastic wave (GEW) dispersion in MATLAB.

GEWtool is an advanced system to compute and postprocess guided elastodynamic waves (GEWs) in plates and cylinders. It is simple to use yet provides full access to the computational results as well as the underlying code. You are welcome to contribute to this open-source project.

Features:

  • Multi-layered plates, tubes and rods
  • Super fast, guarantees to find all solutions
  • General anisotropy, dissipation
  • Compute real frequencies, complex wavenumbers, or ZGV points
  • Choose polarization (Lamb/SH/coupled) and parity (S/A)
