In this work GUIGUW v0.1, a Graphical User Interface (GUI) for the computation of stress guided wave dispersive features, is presented. The software exploits Semi-Analytical Finite Element (SAFE) formulations for the calculation of the wave propagation characteristics. The interface allows for the selection of the geometrical, mechanical and frequency related parameters for the computation. Isotropic and anisotropic materials with linear elastic and linear viscoelastic rheological behaviors can be considered. Any waveguide cross-section can be modeled. For each existing wave, the dispersive results can be represented in terms of wavenumber, wavelength, phase velocity, group velocity (for undamped waveguides), energy velocity and attenuation (for damped waveguides). By simply working with the GUI, original results on guided stress waves can be obtained.

Abstract
In this work GUIGUW v0.1, a Graphical User Interface (GUI) for the computation of stress guided wave dispersive features, is presented. The software exploits Semi-Analytical Finite Element (SAFE) formulations for the calculation of the wave propagation characteristics. The interface allows for the selection of the geometrical, mechanical and frequency related parameters for the computation. Isotropic and anisotropic materials with linear elastic and linear viscoelastic rheological behaviors can be considered. Any waveguide cross-section can be modeled. For each existing wave, the dispersive results can be represented in terms of wavenumber, wavelength, phase velocity, group velocity (for undamped waveguides), energy velocity and attenuation (for damped waveguides). By simply working with the GUI, original results on guided stress waves can be obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
