Relation of collagen fiber orientation to some mechanical properties of human cortical bone.

Mechanical Properties of Needle-Punched Fabrics in Relation to Fiber Orientation

Relative Effects of Collagen Fiber Orientation, Mineralization, Porosity, and Percent and Population Density of Osteonal Bone on Equine Cortical Bone Mechanical Properties in Mode-specific Loading

INTRODUCTION Predominant collagen fiber orientation (CFO) can significantly influence the mechanical properties of cortical bone (e.g., Martin and Ishida, 1989; Martin and Broadman, 1993; Riggs et al., 1993). Previous studies have demonstrated that CFO is a strong predictor of tensile, compressive, or bending strength. Few of these studies, however, have examined the relative effects of CFO, m...

Preferred collagen fiber orientation in the human mid-shaft femur.

Collagen fiber orientation is one aspect of the microstructure of bone that influences its mechanical properties. While the spatial distribution of preferentially oriented collagen is hypothesized to reflect the effects of loading during the process of aging, its variability in a modern human sample is essentially unknown. In a large sample (n = 67) of autopsied adults, the variability of colla...

An investigation of the effects of osteoporosis, impact intensity and orientation on human femur injuries: a parametric finite element study

Objective: Femur is the strongest, longest and heaviest bone in the human body. Due to the great importance of femur in human body, its injury may cause large numbers of disabilities and mortality. Considering various effective parameters such as mechanical properties, geometry, loading configuration, etc. can propel the study to the trustable results.. Methods: A 3D finite element model of the...

The influence of collagen fiber orientation and other histocompositional characteristics on the mechanical properties of equine cortical bone.

This study examined relative influences of predominant collagen fiber orientation (CFO), mineralization (% ash), and other microstructural characteristics on the mechanical properties of equine cortical bone. Using strain-mode-specific (S-M-S) testing (compression testing of bone habitually loaded in compression; tension testing of bone habitually loaded in tension), the relative mechanical imp...
