Abstract

The correlation between the mesostructure of cancellous bones, revealed by scanning electron microscopy (SEM), and the mechanical dynamical behaviour as a function of temperature, was studied. The study of the physical and chemical changes in cancellous bones at temperatures over the room temperature through mechanical dynamical tests requires mandatorily the examination of the mesostructure by means of SEM. SEM studies reveal that the contraction of the woven part of bone occurs by heating over 350K. This change in the morphology of the sample at mesoscopic level influences strongly the dynamic response of bones and consequently masks the physical and chemical processes occurring in the collagen during the heating of samples.
