摘  要:试验采用30~35岁年龄组,男性坚固无损的干燥尺骨与35岁男性死后仅12小时冷藏新鲜尺骨,均截取相同的部位,制成整体试件,分12组,分别在ZDM-10型万能材料试验机、Y型杠杆引伸仪或用应变片在YJ-5型电阻应变仪上进行测定, 描绘出应力应变曲线:且将干燥尺骨与新鲜尺骨的测试结果做了对比。Mechanical properties of undamaged dry ulna bone were studied and results compared with fresh ulna,The adult dry ulna bone and adult fresh ulna were resected in similar regions to be used as 1.2-group specimens respectively for determination. The results were as follows:1.For dry ulna:The compression modulus of elasticity in load-increase was equal to 20.91GPa and in load-decrease,21.4GPa, the compression strength was 152. 188GPa.The tensile modulus of elasticity in load-increase was equal to 20.981GPa and in load-decrease, 22.02GPa. The tensile strength was 159GPa.2.For fresh ulna:The compression modulus of elasticity in load-increase was equal to 19.502GPa and in load-decrease, 19.64GPa; the compression strength was 96GPa.The tensile modulus of elasticity in load-increase was equal to 18.914GPa and in load-decrease,19.698GPa,the tensile strength Was 118GPa.
