Micromechanics of bone strength and fracture
Journal of Biomechanics, 1993The mechanical properties of bone were modeled in the context of a filled polymeric composite containing a collagenous matrix and a hydroxyapatite filler. The longitudinal and transverse moduli of cortical bone as a composite with perfect alignment of filler particles were calculated to be 34.5 and 5.3 GPa, respectively.

Strength and fracture of grasses
Journal of Materials Science, 1991The strength of leaves from six grasses of sclerenchyma content from 2% to 30% has been measured. The strength of sclerenchyma is 144 M Pa. As long as the sclerenchyma fibres are mechanically separated laterally, they toughen the leaf by reducing its sensitivity to damage.

Strength and fracture of aluminum alloys
Materials Science and Engineering: A, 2000Abstract In aluminum alloys, it is general that dimple type fracture occurs from inclusions or second phases particles. Intergranular, local shear and delamination type fractures are also sometimes observed. On Al–Li alloy (A2091), effect of inclusion particles on fracture behavior is analyzed using HRR singularity and Eshelby type internal stress ...

Strength of internal fixation for calcaneal fractures
Clinical Biomechanics, 1998OBJECTIVE: To compare the strength of two types of fixation method for calcaneal fractures. DESIGN: A biomechanical testing examined the stability of 12 fractured calcaneal specimens fixed with two different methods. BACKGROUND: Though anatomic reduction and internal fixation for the treatment of intra-articular fractures of the calcaneus has become ...

The comparative strength of laryngeal fracture fixation
American Journal of Otolaryngology, 1998To assess the fixation strength provided by miniplate fixation, wire-tube batten fixation, and wire fixation alone in repair of thyroid cartilage.Segments 2.5-cm wide x 1-cm long were cut from three fresh, frozen, human cadaveric larynges from an 83-year-old man, a 58-year-old woman, and an unknown cadaver.

The fracture strength and frictional strength of Weber Sandstone
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1975Abstract The fracture strength and frictional strength of Weber Sandstone have been measured as a function of confining pressure and pore pressure. Both the fracture strength and the frictional strength obey the law of effective stress, that is, the strength is determined not by the confining pressure alone but by the difference between the confining

The development of fracture toughness and fracture strength in posterior restorative materials
Dental Materials, 1987Abstract The changes which take place in the fracture toughness (K IC ), the fracture stress and the inherent flaw size with storage time (in water at 37°C) have been determined for three commercial products, all which have been suggested as alternatives to amalgam.

Journal of Materials Engineering and Performance, 2006
To theoretically calculate the strength coefficient and the strain-hardening exponent with conventional mechanical property parameters, formulas relating them with fracture strength and fracture ductility are studied using test data for ten alloys. The applicability of the traditional formula relating these four material constants is discussed first ...

Strength and Fracture of Paper
Trans. of the Xth Fund. Res. Symp. Oxford, 1993, 1993In spite of forty years of research, it is still unclear how the mechanical properties of paper, particularly strength, depend on the disordered geometry of the fibrous network. Most of our understanding of the fracture phenomena of paper is based on illustrative microscopic observations.
