Post-yield Behavior of Human Cortical Bone is Transversely Isotropic in Compression
INTRODUCTION Bone quality is largely dependent on the toughness of the tissue since age-related degradation in toughness makes bone more susceptible to fracture [1]. The observed decrease in bone toughness with age is mainly due to significant decreases in the capacity of the tissue to dissipate energy during the post-yield deformation [2]. Thus, understanding the post-yield behavior of bone is...
متن کاملRelation of collagen fiber orientation to some mechanical properties of human cortical bone.
The percentage of dark. light, and intermediate osteons and their fragments. a\ seen in polarized light, was determined for 53 cross-sections of emhalmed, adult human bone. Dark osteons have collagen fibers predominantly parallel with the long axis of the osteon while in light osteons the fibers are at a sharp angle to the long axis of the osteon. Intermediate osteons
متن کاملOrientation dependence of progressive post-yield behavior of human cortical bone in compression.
Identifying the underlying mechanisms of energy dissipation during post-yield deformation of bone is critical in understanding bone fragility fractures. However, the orientation-dependence of post-yield properties of bone is still poorly understood. Thus, the objective of this study was to determine the effect of loading direction on the evolution of post-yield behavior of bone using a progress...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولAnisotropy Nanoindentation Properties of Human Cortical Bone
INTRODUCTION Cortical bone is an anisotropic material, and its mechanical properties are determined by its composition as well as its microstructure. On the microstructure level (a few microns), cortical bone is composed primarily of single osteons and interstitial lamellae. Nanoindentation has been shown to be an effective technique to probe mechanical properties of microstructures at the micr...
