Abstract:
A two-dimensional plain strain finite element model of infinite isotropic solid has been developed to investigate the ultrasonic wave scattering by a cylindrical hole. The results, presented in the form of displacement snapshot, and divergence and curl snapshot, are compared with the previous observations obtained with the dynamic photoelasticity method. Good agreement is found. By processing the data, screw creeping of the incident compression wave along the hole can clearly be seen, verifying a theoretical prediction and compensating for the deficiency of experimental results.
