RISEstimation of Bone Matrix Apparent Stiffness Variation Caused by Osteocyte Lacunar Size and Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The role of osteocyte lacunar size and density on the apparent stiffness of bone matrix was predicted using a mechanical model from the literature. Lacunar size and lacunar density for different ...
Analytical Approach to Recovering Bone Porosity From Effective Complex Shear Modulus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work deals with the study of the analytical relations between porosity of cancellous bone and its mechanical properties. The Stieltjes representation of the effective shear complex modulus ...
Increased Microstructural Variability is Associated With Decreased Structural Strength But With Increased Measures of Structural Ductility in Human Vertebrae
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The lack of accuracy in the prediction of vertebral fracture risk from average density measurements, all external factors being equal, may not just be because bone mineral density (BMD) is ...
Effect of Microcomputed Tomography Voxel Size on the Finite Element Model Accuracy for Human Cancellous Bone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The level of structural detail that can be acquired and incorporated in a finite element (FE) analysis might greatly influence the results of microcomputed tomography (μCT)-based FE simulations, ...
Evaluation of Filler Materials Used for Uniform Load Distribution at Boundaries During Structural Biomechanical Testing of Whole Vertebrae
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study was designed to compare the compressive mechanical properties of filler materials, Wood’s metal, dental stone, and polymethylmethacrylate (PMMA), which are widely used for performing ...
