Dispersion Calculator v3.2

Calculate guided wave dispersion diagrams for isotropic plates, rods, and pipes as well as for multilayered anisotropic laminates.

Description

The MATLAB-based Dispersion Calculator (DC) is an interactive software for calculating the phase velocity, energy velocity, and attenuation dispersion as well as mode shapes of guided waves in isotropic plates, rods, and pipes as well as multilayered anisotropic laminates. Fluid-loading and viscoelasticity can be considered. Polar dispersion diagrams can be calculated for anisotropic specimens. DC uses the Rayleigh-Lamb equations for isotropic plates, the corresponding equations for isotropic cylindrical waveguides, and the stiffness matrix method (SMM) combined with the transfer matrix method (TMM) for multilayered anisotropic plates (see literature below). DC is continuously improved and validated by using DISPERSE. DC was first released in 2018, and is used worldwide today. For more information, read…
