As finite element models can be tailored to specific individual anthropometry
sex and age
there is a need for refined material properties. This study contributes to this effort by generating new data for the agedependence in bone material properties in males. The left tibiae and femora were extracted from five male subjects aged 15 (pediatric subject)
37 and 40 (adult group)
and 72 and 75 (elderly group). Small bone coupons were machined and tested under tensile load. The pediatric coupons (n = 15) were tested under quasi-static loading (~ 0.5 %/s). For the adult and elderly subjects (n = 16)
two coupons were harvested next to each other to create matched pairs: one was tested under quasi-static loading and the other one was tested under dynamic loading (~ 100%/s). An optical stereophotogrametric non-contact system was used to measure the strain field on the outermost surface of each coupon...
