Multi-Parameter Nano- and Micro-Mechanical Characterization of Biomaterials
The objective of this work is to experimentally determine and model the mechanical behavior of biomaterials such as  bone, connective tissue, and bio-polymers, using nano- and micro-indentation techniques. Multi-parameter modeling of mechanical properties and estimation of the stresses and strains that occur are considered the key elements of this research.
