Wavefrom Revealer

The ‘WaveFormRevealer 1.0’ calculates for the analytical waveforms under arbitrary engineering situations for PWAS excited wave propagation in plate or thin wall structures. ‘Arbitrary’, hereby, means different kinds of materials, various setup geometries (plate thickness, PWAS distance, and PWAS size), and any kind of excitation signal desired by the users. This software also allows users to obtain the theoretical solution for dispersion curve, tuning curve, frequency components for S0 and A0 wave mode, and the plate transfer function.

The software GuidedWaves derives the dispersion curves for composite plates with stacking sequence of the type
[(
f1,f2,…,fn)N]S where each layer is made of unidirectional fibers. The layers can have different material properties, but same thickness. The output is the values of the phase velocities versus the wavenumber-thickness product where the thickness is the total thickness of the plate.
