Application of theoretical models of nonlinear boundaries to the investigation of adhesive bonding conditions

It is expected that for adhesive defects, much of the critical nonlinear behaviour will occur in the narrow (thickness /spl Lt/ /spl lambda/) adhesion interface regions. Here we treat the interesting parts of the problem by considering the system as a single layer with nonlinear interfaces. Wave propagation in this system is investigated in the time domain using a normally incident longitudinal plane wave and compared directly to experimental results.
