2019, Master of Science, Ohio State University, Mechanical Engineering.
Elastodynamic characterization of adhesive layers at bimaterial interfaces is important in the field of adhesive bonding. The present thesis is an investigation of the mechanical behavior of adhesive interfaces using spring models and cohesive zone models. Linear and nonlinear spring models were considered, where the nonlinear behavior was approximated using piece-wise linear segments. Horizontally polarized shear (SH) waves were used as the body force input in this study. A boundary element methodology (BEM) was developed, which adopts either linear spring or nonlinear spring or cohesive boundary conditions, for potential use by an NDE practitioner in the non-destructive evaluation of adhesive bonds. The BEM results, along with ultrasonic measurements, provide insight into damage characterization of adhesively bonded structures.
