Moving finite elements and dynamic vehicle interaction

An Investigation Into the Vehicle-Curved Bridge Dynamic Interaction

dynamic soil – structure interaction analysis of concrete structures by using finite elements method

in practice, foundations are settled on the soft layers of soil, so the ground must be designed as well as the structure. wave propagation and hysteresis damping of soil layers may alter the seismic response of flexible-base design in comparison to controversial fixed-base. lots of uncertainties about this issue, necessitate most of seismic design standards including iranian standard no. 2800 t...

A Geometrical-mechanical Interpretation of Gradient-weighted Moving Finite Elements

The usual explanation of the gradient-weighted moving finite element (GWMFE) method has been in terms of its variational interpretation. This paper presents a more intuitive geometrical-mechanical interpretation of GWMFE as a balance of forces on the nodes, forces concentrated onto the nodes by the laws of leverage. It also presents significant simplifications in the “internodal viscosity” term...

Dynamic Response of the Coupled Vehicle-Floating Slab Track System using Finite Element Method

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
