• ANSYS Tutorial: Piezoelectric Wafer Active Sensor (PWAS) Impedance Simulation [link]

• Guided Waves Dispersion Curves in Composite Materials [Download]

The software GuidedWaves derives the dispersion curves for composite plates with stacking sequence of the type
[(f₁,f₂,…,f_n)_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.
