【摘要】 我们对新鲜尸体短管状骨进行了机械性能的测试,提供了骨弯曲、扭转、冲击各项试验结果和受力分析及各种应力引起骨断裂的形态。实验结果证明,人体短管状骨和长管状骨一样,是一种具有脆性和塑性两方面特点的生物材料,而骨干部较接近脆性生物材料,干骺部则较接近塑性生物材料。更多还原

【Abstract】 From December 1983 through December 1984, the mechanical properties of fresh short tube bones of the corpses of g persons suddenly dying of fatal injuries were measured and various fracture models were studied.One hundred and thirty - five intact short tube bones, including the metacarpal, phalangeal and metatarsal bones were tested on Amsle material testing machine.It is concluded that human short tube bones, just as the long tube bones, have both brittle and plastic characteristics; and that while the diaphysis is similar to brittle material, the metaphysis is similar to plastic material.The data presented in this paper may be used for reference in further studies of certain biomechanical problems of long and short tube bones.A discussion and analysis of the fracture types by various stresses are also presented.更多还原
