DOI: 10.1007/s10706-017-0244-6
Abstract: Small-strain damping is a key factor of soil behavior under cyclic loading: although the value of small-strain damping is such small that would not compete with damping at larger strains (that would have a more… read more here.

DOI: 10.1007/s10706-017-0436-0
Abstract: It is known that the construction over soft clay is always a great challenge to the geotechnical engineers. The soft clay poses high compressibility and low bearing capacity. It is a common practice to construct… read more here.

DOI: 10.1007/s11440-017-0567-8
Abstract: Abstract Foundation soils are often under non-proportional cyclic loadings. The deformation behaviour and the mechanism of non-coaxiality under continuous pure principal stress rotation for clays are not clearly investigated up to now. In order to… read more here.
