... mechanism remains unknown. Simulative research on the mechanical effects of LIPUS on disuse trabecular bone and osteoblasts have been performed. The von Mises stress of disuse trabecular bone and osteoblasts obviously increased under LIPUS irradiation. The average von Mises stress of osteoblasts were two...

...: Brian D. Stemper. 25 09 2013 02 05 2014 14 05 2014 Most studies investigating human lumbar vertebral trabecular bone (HVTB) mechanical property–density relationships have presented results for the superior–inferior (SI), or “on-axis” direction. Equivalent, directly measured...

... in loading, osteoclast activation frequency, osteoblast formation rate, and osteocyte mechanosensitivity by comparing results of the analytical model with those of the micro-finite element model that simulates bone remodeling at the cellular level. With the new theory, trabecular bone...

... anisotropy nondestructive imaging modulus trabecular bone inverse problems Many tissues, such as cancellous bone, tendon, and arterial walls, are anisotropic materials that can display substantial variations in material properties even within a single anatomic site. For example, spatial...

...Srinidhi Nagaraja; Oskar Skrinjar; Robert E. Guldberg Although microdamage is known to accumulate in trabecular bone with overloading and aging, the tissue-level stresses and strains associated with local bone failure are not well known. Local correlation of microdamage with microstructural...

... and finite element (FE) method, respectively. Three different three-dimensional quasi-static models, including a horn model with trabecular bone, a horn model with compact bone that instead of trabecular bone, and a horn model with trabecular bone as well as frontal sinuses, were studied. FE simulations were...

...Mathieu Charlebois; Michael Pretterklieber; Philippe K. Zysset Osteoporosis-related vertebral body fractures involve large compressive strains of trabecular bone. The small strain mechanical properties of the trabecular bone such as the elastic modulus or ultimate strength can be estimated using...

...Congyu Wang; Liang Feng; Iwona Jasiuk We study apparent elastic moduli of trabecular bone, which is represented, for simplicity, by a two- or three-dimensional periodic cellular network. The term “apparent” refers to the case when the region used in calculations (or specimen size) is smaller than...

... selected within our investigation is not as sensitive to individual pixel outliers. Strain calculation by image registration applied to trabecular bone takes advantage of large contrast differences between marrow and bone; this structure limits the strain resolution possible. Bone structure was shown...

...Vikas Tomar Trabecular bone fracture is closely related to the trabecular architecture, microdamage accumulation, and bone tissue properties. Micro-finite-element models have been used to investigate the elastic and yield properties of trabecular bone but have only seen limited application...

...Xiang Wang,; Xiangyi Liu, and; Glen L. Niebur The Orientation of trabecular bone specimens for mechanical testing must be carefully controlled. A method for accurately preparing on-axis cylindrical specimens using high-resolution micro-CT imaging was developed. Sixteen cylindrical specimens were...
