In the analysis, firstly, the flux boundary condition is used to simulate the frictional heat resource between wheel and rail. The non-steady heat transfer between the contacting surfaces of the wheel/rail, heat-convection and radiation between the wheel/rail and the ambient were all taken into consideration. Therefore, a heat coupling model of the wheel/rail in rolling/sliding is put forward to calculate the frictional temperature rise in the wheel and rail. Secondly, after the temperature distribution of wheel/rail, due to friction, is calculated, substitute the thermal load with equivalent fictitious body force and boundary distributed force loaded on the nodes of the corresponding elements. The wheel-load is applied to the center of the wheel.

And the frontal technique is adapted to solve the FE equations. The techniques are studied to deal with the large slip frictional contactproblems between a deflectable body with large deformation and a rigid bodywith flat or curved surface. A new algorithm is presented to resolve such contactproblems, including incremental displacement constraints and force constraints,and the modules are programmed. The performances of tire under static load invertical loading state and camber state are analyzed by this method.

The pseudo-static test which subjects to horizontal load on the A-type autoclaved aerated concrete block wall was adopted. Reinforced concrete beams were set up at the upper and lower ends of the test block, and the four-bar linkage device was provided to ensure that the top of the wall was only in translatory motion, not in rotation at the level force. Hydraulic synchronous loading device was adopted to simulate the vertical load which was produced by the wall of the housing interlayer.

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.
