A 3D Shear Material Damping Model for Man-Made Vibrations of the Ground

Abstract

In this article, a 3 dimensional shear damping constitutive soil model is presented. This model has been implemented as a user defined soil model for the Finite Element Method software of Plaxis 2D. Verification tests demonstrate a good agreement with the theoretical model. A pulse load on a circular area on a soil surface has been numerically modelled with this shear damping soil model and compared to the results obtained by using the Rayleigh damping. The shear damping model demonstrates a different physical behaviour of the soil, in comparison to the Rayleigh damping.
