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. 2014 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1417706326 http://rave.ohiolink.edu/etdc/view?acc_num=osu1417706326 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
