Reflection and transmission of elastic waves at a loosely bonded interface between an elastic and micropolar elastic solid

The problem of reflection and transmission of plane periodic waves incident on the loosely bonded interface between an elastic solid and a micropolar elastic solid is discussed with the assumption that the interface behaves like a dislocation which preserves the continuity of stress allowing a finite amount of slip. It is further assumed that the normal displacement is continuous and the shearing stress is proportional to the velocity of the slip. Amplitude ratios are computed numerically for a particular model and are plotted for different degree of bonding parameter. Two special cases have been discussed.
