A number of new methods and computational procedures have been developed after World War II. Building of damaged cities and enterprises in such huge extent all over the world necessitated using of new methods and ideas in all areas of human activities. The theoretical treatments were supported in those years by new very effective tools – computers. New numerical methods developed for computers allowed scientists and engineers to solve very complicated and complex problems from practice.

The support of innovations, education and research of factors influencing the sustainable growth and competitiveness is strongly emphasized in the documents of European Union. The research and development, design, production, marketing and customer support are more integrated so they work together as a one part virtually connecting the customers and car producers. The car is a multi-material vehicle in present, therefore the knowledge of its physical, chemical and mechanical properties is necessary to combine with required properties of future car body components.

Friction including wear and lubrication is one of the most familiar physical phenomena and has been investigated from ancient age till now. Tribology as the science and technology of interacting surfaces in relative motion includes the study and application of the principles of friction, lubrication and wear. Any product where one material slides or rubs over another is affected by complex tribological interactions, whether lubricated or unlubricated (as in high temperature sliding wear in which conventional lubricants cannot be used but in which the formation of compacted oxide layer glazes can be observed to protect against wear).
