Transient SH-Wave Interaction with a Cohesive Interface

2014, Master of Science, Ohio State University, Mechanical Engineering.
Characterization of material damage at the interface between two bodies using non-destructive evaluation (NDE) techniques is a field of study that is important from the point of view of both, research and application. In order to provide useful design engineering tools to the practicing engineer in the field of NDE it is necessary to build robust models that can be easily implemented. In the present thesis SH body waves are chosen as a representative candidate to assess material damage and degradation at an interface. In addition a well-established material damage law in the form of cohesive zones from fracture mechanics is considered. The combined effects of transient wave motion and the cohesive boundary condition at the interface are studied in order to develop a methodology for potential use in an NDE application scenario. Parameter variation studies offer promising results to the practicing engineer. Specifically, the trends of displacement and traction along the interface are evaluated between the bonded and damaged material conditions. Parameter variations allow for insight into how altering the material parameters and wave setup affect macro-behavior of the interface.
