In this model, the contact behavior is represented through effective interface stiffnesses. We have developed a micromechanical methodology for determining complex-valued effective normal and shear interface stiffnesses by considering asperity contact interactions. The methodology incorporates effects of surface roughness, anisotropy, existing stress conditions and rate-dependent asperity contacts. We use the derived effective stiffnesses to elucidate wave transmission phenomena exhibited by interfaces. © 2008 American Institute of Physics.||URI:||https://ktisis.cut.ac.cy/handle/10488/14367||ISBN:||0094243X||DOI:||10.1063/1.2902551||Type:||Conference Papers|
