Numerical study of the time-of-flight pulsed ultrasonic polar scan for the determination of the full elasticity tensor of orthotropic plates KU Leuven Universiteit Gent
A novel approach is presented for the ultrasonic determination of the elastic constants in plate-like structures of an orthotropic material (e.g. composites) using a time-of-flight version of the pulsed ultrasonic polar scan (TOF P-UPS). A forward numerical model of the TOF P-UPS is coupled to an inversion algorithm, based on the genetic optimization principle, targeting the determination of the orthotropic elastic parameters, and the quality of ...
