1. 1. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Olivia Karlsson; [2022]
   Nyckelord :Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

   Sammanfattning : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. LÄS MER

3. 2. Segmentation, Analysis, and Modelling of Microstructure in Cortical Bone, based on X-ray Microtomography

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Elin Törnquist; [2017]
   Nyckelord :Cortical bone; Biomechanics; Segmentation; K-mean clustering; Microstructure; X-ray Microtomography; Mathematics and Statistics; Medicine and Health Sciences; Technology and Engineering;

   Sammanfattning : The microstructure in cortical bone greatly affect the toughness of the bone and the crack propagation during fracture. The two main structural features, Haversian canals and osteons, have been previously studied in order to increase the knowledge of the biomechanics of bone. LÄS MER
