Resonant frequency and strength of rabbit humeri

First flexural resonant frequency, length, midshaft width, and mineral content were measured in 112 excised rabbit humeri prior to recording load deflection curves in three-point bending. Breaking strength, bending stiffness, mineral content, resonant frequency, and the geometric measurements were all correlated by regression analysis and with a simple analytical model. The breaking strength of rabbit humeri estimated by regression analysis (r=0.869) was not as effective as that for embalmed human ulnae (r=0.947). In addition, the simple analytical model was not as effective in estimating resonant frequency in rabbit humeri (r=0.477) as in human ulnae (r=0.70)
