Abstract and keywords

Bone properties are changing during a human life, e.g. bone mineral density is decreasing. Hence, bones of elderly people do not withstand loads which are still manageable by young people. The objective of the study was to establish a methodology to predict and adjust thresholds for forcedeflection curves according to gender, age, rib cross-section and rib mineral density. Specimens of five fresh post mortem human surrogates were examined. Bone mineral density was measured and specimens were subjected to 3-point-bending tests. The findings could be used to limit loading corridors of ribs in human body models according to gender aspects.
