Abstract Details

2017, Master of Science, Ohio State University, Mechanical Engineering.
Understanding wave phenomena at material interfaces is an important problem in non-destructive evaluation / material characterization. Modeling the behavior of the interface presents interesting opportunities in this field. The present work attempts to understand the effect of an interface on transient and steady-state wave propagation through a bi-material system. Horizontally polarized shear waves (SH) are chosen as candidates in the analysis. The interface itself is considered to be spring-like with non-linear load-displacement characteristics. The non-linear behavior of the spring can easily be treated as approximate linearized segments. Transient analytical solution forms for reflected and transmitted waves are obtained by considering linear spring interface model using Cagniard-de Hoop technique. Numerical results for time-harmonic SH wave interaction are obtained considering a non-linear spring model using perturbation technique. The methodology presented should enable a practicing engineer to draw insights into interface strength / damage.
