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