Abstract: The dynamic impedances of a vertically or torsionally excited viscoelastic soil layer with a thin disturbed zone around the edge of a central circular hole are evaluated and compared, over a range of parameters, with those ...

Abstract: A study of the dynamic impedances for radially inhomogeneous, infinite viscoelastic layers with a circular hole, and for piles embedded in a medium represented by such layers is made. Systems in vertical and torsional modes ...
