EFFECT OF CONTACT AREA ON MECHANICAL IMPEDANCE MEASUREMENTS,

Abstract:
The weighted average normal mechanical impedance of a circular area on an elastic half space does not depend markedly on the assumed pressure distribution. Its absolute value is almost independent of frequency at least until the wavelength is equal to the circumference of the circular contact area, but the loss tangent varies almost linearly with frequency up to a value of about one at this cut-off. These conclusions are only valid for structures large compared with a wavelength. Author
