A New Method to Determine Trabecular Bone Elastic Properties and Loading Using Micro Mechanical Finite-element Models
The apparent mechanical behavior of trabecular bone depends on properties at the tissue or trabecular level, M any investigators have attempted to determine trabecular tissue properties and loading. However, accuracy and applicability of all methods reported are limited. The small size of the trabeculae and a possible size effect are complicating factors when using traditional testing methods o...

متن کاملIndirect determination of trabecular bone effective tissue failure properties using micro-finite element simulations.
Trabecular bone strength is marked not only by the onset of local yielding, but also by post-yield behavior. To study and predict trabecular bone elastic and yield properties, micro-finite element (micro-FE) models were successfully applied. However, trabecular bone strength predictions require micro-FE models incorporating post-yield behavior of trabecular bone tissue. Due to experimental diff...
متن کاملMicro-finite element simulation of trabecular-bone post-yield behaviour--effects of material model, element size and type.
Micro-finite element (micro-FE) analysis became a standard tool for the evaluation of trabecular bone mechanical properties. The accuracy of micro-FE models for linear analyses is well established. However, the accuracy of recently developed nonlinear micro-FE models for simulations of trabecular bone failure is not known. In this study, a trabecular bone specimen was compressed beyond the appa...
متن کاملIdentification of elastic properties of human patellae using micro-finite element analysis.
Current homogenized finite element (hFE) models of the patella lack a validated material law and mostly overlook trabecular anisotropy. The objective of this study was to identify the elastic constants of patellar trabecular bone. Using μCT scans of 20 fresh-frozen cadaveric patellae, we virtually extracted 200 trabecular cubes (5.3mm side length). Bone volume fraction and fabric tensor were me...
