【摘要】 本文应用Hopkinson杆应力技术研究人体颅骨动态冲击力学性质。人体运动过程中有可能遇到各种机械作用包括冲击载荷的作用。此时,骨将在动态载荷作用下,骨损伤大部分与此冲击载荷相关。由于骨在准静态实验中的力学参数同高应变率下有显著差别,因而了解骨在高应变半下的力学性质非常重要。本文给出了在准静态、低应变率和高应变率下人体颅骨的各向异性性质的不同实验结果。更多还原

【Abstract】 The Hopkinson bar stress technique has been used to investigate the dynamic impact mechanical properties of Human skull. However, a body may be subjected to various mechanical process including impulsive loading. Under such circumstance, bones in the body would be deformed at dynamical loading.Wounds of bones are often resulted of these impulsive loadings.It is of importance to know the mechanical behavior of bone at high strain rate since the mechanical parameters are significantly different from those determined by quasi-static test.In this paper, the experimental results of anisotropic behaviour for human skull bone at quasi-static, low strain rate and high strain rate are presented,更多还原
