Design of geotechnical engineering problems that involve vv{+p(~**O
dynamic loading of soils and soil–structure interaction d!YP{y P
systems requires the determination of two important j%^4

parameters, the shear modulus and the damping X;Sb^c"j1
of the soils. The recent developments in the numerical _vDmiIn6 K
