Investigation of stress state and contact pressures in contact area of journal bearing by numerical simulation Štefan Hajdu1, a 1 Slovak University of Technology in Bratislava, Faculty of Materials Science and Technology in Trnava, Institute of Production Systems and Applied Mechanics, Department of Applied Mechanics, Rázusova 2, 917 24 Trnava, Slovak Republic astefan.hajdu@stuba.sk Keywords: Tribology, Contact problem, simulation, FEM, ANSYS Abstract.
If we want to know more about tribological processes we will have to know stress state in the materials loaded through contact interaction between two bodies to the last detail.
The friction coefficient is constant only for a given pair of friction materials and defined state of the environment.
It changes with change of materials and operating conditions.
Mainly shear component of stresses are very important for the creation of the fatigue wear in ductile materials.

Environmental system includes water, air, soil and organism, which correlate and co-restrain with the flows of material, energy and information.
Therefore, environment system is not only a raw material pool for human survival and development, but also a waste pool emitted by human activities.

The key failure areas with current materials are structural failures seen in plastics, durability of wooden materials, and the heavy weight of stainless steel components.
The drawback when comparing metal materials to plastics is the added weight.

And it is very important and useful to biomedicine science and engineering that evaluating correctly the mechanical property of the equivalent materials with human skin’s nature.
Thereby, the equivalent material of human skin keeps some nonlinear elastic specificity for the strain-stress relation of elastic materials.
According to the experiment method, the same skin organ materials are contrastingly tested in different conditions [3].
