Real–time observation of trabecular bone microstructure during micromechanical testing

Abstract eng:
The paper deals with investigation of trabecular bone microstructure using real–time microtomography. Recorded μCT scans are used to record spatial mechanical behaviour of bone under loading and provides detailed information about inner architecture and hierarchical structure of bone tissue. Micro-FE models developed on basis of the μCT scans of the undeformed microstructure are used to investigate different material models suitable to describe bone tissue at the trabecular level. Overall, real–time microtomography enables microdamage detection in real-time during mechanical testing and provides a correlation to recorded stress strain curves.
