Tensile Properties of Orthodontic Elastomeric Chains

Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2010
Orthodontic elastomeric chains are a main component in orthodontic therapy employing labial or lingual appliances. The aim of this study was to investigate the tensile properties of orthodontic elastomeric chains with a test setup according to ISO 21606:2007.Orthodontic elastomeric chains of eight manufacturers with and without an intermodular link ...

Tensile and compressive properties of cancellous bone

Journal of Biomechanics, 1991
The relationship between the mechanical properties of trabecular bone in tension and compression was investigated by non-destructive testing of the same specimens in tension and compression, followed by random allocation to a destructive test in either tension or compression.

Tensile properties of twisted hair fibers

International Journal of Cosmetic Science, 2005
Hair is routinely twisted during grooming processes, which can cause tangles and lead to breakage of hair fibers. To evaluate the damage caused by twisting hair, the tensile stress–strain properties of single twisted hair fibers were measured by two different experimental procedures: (A) twist at constant length, followed by extension to break (without

Dynamic tensile properties of human placenta

Journal of Biomechanics, 2008
Automobile crashes are the largest cause of injury death for pregnant females and the leading cause of traumatic fetal injury mortality in the United States. Computational models, useful tools to evaluate the risk of fetal loss in motor vehicle crashes, are based on a limited number of quasi-static material tests of the placenta.

Modeling of Tensile Properties

2009
AbstractA computational tool would require the contribution of the strengthening mechanisms of metallic material to be predicted and then summed in an appropriate way to derive an estimate of the tensile properties. This article focuses on the modeling of deformation mechanisms pertinent to structural materials, namely, solid-solution strengthening ...

Some tensile properties of elastic tissue

Biochimica et Biophysica Acta, 1954
Abstract Load-extension curves of strips of ox ligamentum nuchae in the extension range 0–20% may be repeated several times without change. Use of this observation has been made in studying the effects of various chemical treatments of the material on its mechanical properties. The results have been interpreted in terms of the structure of the tissue.

Tensile and tear properties of dental dam

Journal of Endodontics, 1996
The tensile and tear properties of highly extensible latex are sensitive to specimen shape. Three specimen shapes (ASTM D412 Die C dumbbell tensile specimen, rectangular tensile specimen with 1.74 mm hole, and ASTM D624 Die C tear specimen) were evaluated for proposed ANSI/ADA specification #90 for dental dams.

Tensile properties of the annulus fibrosus

European Spine Journal, 1993
Part I of this study showed that collagen fibres do need not need to be continuous to reinforce the annulus fibrosus, and that 15-mm-wide samples of annulus retain about 44% of their in situ stiffness and strength when stretched vertically. Part II investigated the ultimate tensile strength (UTS) and fatigue life of such samples.

Tensile properties of the in vivo human gastrocnemius tendon

Journal of Biomechanics, 2002
In the present experiment we obtained the tensile properties of the human gastrocnemius tendon, a high-stressed tendon suitable for spring-like action during locomotion. Measurements were taken in vivo in six men. The gastrocnemius tendon elongation during tendon loading-unloading induced by muscle contraction-relaxation was measured using real-time ...

Study of the Tensile Properties of Living Skin Equivalents

Bio-Medical Materials and Engineering, 1995
The living skin equivalent is one of the more advanced clinical applications in the field of tissue engineering. It is a promising therapeutic option for bum victims and a strong potential for manifold in vitro experiments. However, researchers have encountered major drawbacks in the reconstruction of the dermal layer.
