| Abstract: | 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. |
