Analysis of fracture processes in cortical bone tissue
Bones are the principal structural components of a skeleton; they play unique roles in the body providing its shape maintenance, protection of internal organs and transmission of forces. Ultimately, their structural integrity is vital for the quality of life. Unfortunately, bones can only sustain loads until a certain limit, beyond which they fail. Understanding a fracture behaviour of bone is ...
متن کاملCortical Bone Fracture
The structural integrity of ‘‘hard’’ mineralized tissues such as bone is of great importance, especially because bone is the primary structural component of the body, serving as a protective load-bearing skeletal framework. As a structural material, bone is unique when compared with other engineering materials because of its wellknown capacity for self-repair and adaptation to changes in mechan...
متن کاملMixed-mode fracture of human cortical bone.
Although the mode I (tensile opening) fracture toughness has been the focus of most fracture mechanics studies of human cortical bone, bones in vivo are invariably loaded multiaxially. Consequently, an understanding of mixed-mode fracture is necessary to determine whether a mode I fracture toughness test provides the appropriate information to accurately quantify fracture risk. In this study, w...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولEvaluation of mode I fracture toughness of cortical bone tissue in the RL crack propagation system
In this work the mode I fracture properties of bone tissue were determined for the RL propagation system. With this aim, Double Cantilever Beam (DCB) fracture tests were performed using specimens of cortical bone tissue harvested from bovine femurs with an age of approximately 8 months. In order to overcome the difficulty associated to the monitoring of crack length during propagation in the co...
