Review of viscoelastic models applied to cortical bone


  • 1. Department of Mechanical, Manufacturing and Biomedical Engineering, Trinity College Dublin


Bone is a composite of the biopolymer collagen type I and the bioceramic hydroxyapatite. Two maintypes of regions are found in bones: cortical - the most important for its mechanical properties - andtrabecular. Viscoelasticity is an essential property of cortical bone. Three viscoelastic models selected inthe existing literature are analysed and compared against each other in this report. Based on the chosenstrain rate range chosen, different models may be suitable to fit the data of an experiment. For mechanicaltesting at a macroscopic scale, a Maxwell-Weichert seems more suitable and adapted to a wider range ofstrain rates. At a microscopic scale, the Burgers model described in this report also provided satisfactoryresults. More extended analysis on the models are provided in this report.
