Coupling resonance mechanism of interfacial fatigue stratification of adhesive and/or welding butt joint symmetric and/or antisymmetric structures excited by horizontal shear waves are investigated by forced propagation analytical solutions derived by plane wave perturbation methods, integral transformation methods and global matrix methods. The influence of materials on the coupled resonance frequency is analyzed and discussed by the analytical methods. Coupling resonance of interface shear stress is a structure inherent property. Even a very small excitation amplitude at the coupling resonance frequency can result in interface shear delamination. The coupling resonance frequency decreases with the increase of interlayer thickness or shear wave velocity difference between substrate and interlayer. The results could be applied to layered and/or anti-layered structural design.

Incident Waves

An analysis of the scattering of horizontally polarized shear waves by a finite crack extending uniformly is carried out. It is based on the extension of the integral equation method used by the authors in wave diffraction problems dealing with stationary lines or surfaces of discontinuity. The distortion of the local stress pattern due to the motion of the crack is determined for incident waves impinging on the crack in an arbitrary direction. It is found that the intensity factor of the singular stresses depends sensitively upon the speed of crack propagation, the frequency of the incoming waves, and the angle of incidence. As the crack speed is increased at normal incidence, the peaks of the intensity-factor curves tend to decrease and to occur at lower wave numbers. Quantitative assessment of the effect of the aforementioned system parameters on the stress and displacement fields is made by displaying the numerical results graphically.
