A time-domain finite element method for dynamic viscoelastic solution of layered-half-space responses under loading pulses
We developed a dynamic viscoelastic response model and finite element solution for layered half-space. The combined Houbolt, central and forward finite difference method is proposed for time discretization. It is able to model the temperature and space-dependent material properties. We validated the approach for a multilayer pavement structure on soil. The dynamic viscoelastic model considering damping could more accurately emulate structural responses.
