332 Computational Modelling of Biomechanics and Biotribology
face considerable dif culties. The fracture process requires a quantitative
description of the problem, which is often dif cult or impossible to pre-
pare due to its complexity. In many cases, de ciencies of such a quan-
titative description realized in the framework of classical methods are
offset by unconventional mathematical tools. Thus, the analysis of surface
properties followed by modelling its desired properties – which in the best
possible way should re ect the real object, namely its generalized proper-
ties – is a current research topic on the border between art and medicine.
It is not easy to construct a general model for such a phenomenon as
fracture, which would take ...
