The Spectral Finite Element Method for Simulating Wave Propagation in Viscoelastic Soils

Abstract

The soil material behavior has been widely modeled with viscoelastic material models; however, choosing the actual material properties within a viscoelastic model is not trivial. This paper presents a rigorous methodology for obtaining the damping and stiffness terms in viscoelastic material model for modeling wave propagation in soils. The viscoelastic material model is calibrated for various deformation modes. The calibrated model is then utilized for simulating wave propagation in soils. The boundary conditions in the far field are treated with non-reflecting boundaries. The present model with calibrated data has a great potential in modeling wave propagations in soils.
