长骨抗压性能

本文旨在对人的湿润的右股骨与右肱骨的试样进行轴向抗压试验,籍此得到股骨的弹性模量E=9.98×109N/m2,肱骨的弹性模量E=11.37×109N/m2.同时,与国内外的有关资料进行了比较以及讨论.本文还指出了骨组织呈现明显的粘弹性性质,滞后(辶回)线示于图3(a)和(b).并对试验过程中的一些力学现象作了解释.

The Compressive Properties of Long Bones

In this study, compressive tests of the bones along the axial direction have been carried out on some wet specimens of the right femur and humerus, from which there have been obtained the elastic modulus of femur E=9.98×109N/mM2 and that of humerus E=11.37×109N/m2. Also comparisons and discussions have been made with reference to the available data reported abroad and at home.As indicated in this paper, bone tissues obviously possess viscoelastic properties. Their hysteresis loops are shown in Fig. 3 far and (b) and some mechanical phenomena observed during the test are illustrated elsewhere.
