We consider a general mathematical model which describes the quasistatic contact of deformable body with an obstacle, so-called foundation. The material’s behaviour is modeled visco-elastic-type constitutive law and described interface associated to version Coulomb’s dry friction. list assumptions on data provide relevant examples laws boundary conditions. Then, we derive two different variatio...

Computation of contact point trajectories and forces exchanged between two bodies in contact are relevant to several disciplines. The solutions proposed in the literature are often too complex to be implemented in real time simulations, especially if rolling effects are considered. In this paper an algorithm for fast simulation of soft-finger contact model with rolling effects is proposed. The ...

Quasi-static frictional contact problems for bodies of fairly general profile that can be represented as half planes can be solved using an extension of the methods of Ciavarella and Jäger. Here we consider the ta...

We present a new approach to modeling contact between rigid objects that augments an individual Coulomb friction point-contact model with rolling and spinning friction constraints. Starting from the intersection volume, we compute a contact normal from the volume gradient. We compute a contact position from the first moment of the intersection volume, and approximate the extent of the contact p...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh-&#10Timoshenko beam elements. The ra...
