Semi-Analytical Finite Element (SAFE) method for plotting Lamb waves dispersion curves of an aluminum plate and comparison with Disperse software

Investigation into ultrasonic Non-destructive evaluation (NDE) methods for assessing complex designs depends firmly on displaying apparatuses that calculate dispersion curves. These expectations are vital empowering the best assessment methodologies to be distinguished and their aversions being assessed. This study, main purpose of this work is do a quantitative SAFE technique by calculating curves (wavenumber, phase velocity, group velocity) comparing them those generated Disperse Software.
