362 Computational Modelling of Biomechanics and Biotribology
Biocompatibility of titanium implants and fasteners speeds up the healing
process and recovery (Weisman, 1968). Details of biomaterials, sample size
and test parameters are deliberately omitted in this paper in order to gener-
alize the methodology presented here for a wide range of biomaterials.
A three-point bending test resulted in obtaining crack surfaces which
contain a map of the material fracture course. The material crack surface
was examined using a sampling step of 156 nm in the X and Y axes. An area
sized 4096 × 4096 measurement points was selected from the whole mea-
sured surface. This resulted in a matrix of height Z , which was a square grid
consisting of 16 777 21 ...
