Solid-Solid Bonding Characterization by Ultrasonic Reflectivity
The most common approach to model a weakened bond at a solid-solid interface has been to allow for a partial slip of the displacement at the interface. This concept is transformed into a specific set of boundary conditions which are then solved to obtain the plane-wave reflection and transmission coefficients or to determine the dispersion relation of the associated interface wave, if they exist. A key question in this approach is whether one allows for a partial slip in both displacement components or just the tangential. Initially, Murty [1–2] considered only the tangential slip to model the slip interface with the following boundary conditions:
Normal stress is continuous,
Shear stress is continuous,
Normal displacement is continuous, and
Shear stress is proportional to a tangential displacement slip.
