Properties of Large Multispot Ultrasonically Welded Joints

Journal of Aircraft, 1980
Using ultrasonic spotwelds, two series of overlap joints were prepared with aluminum alloys and tested in tension. In the first series between 4x12x0.063 in.-thick panels, it is shown that on a one-for-one basis ultrasonic welds produce joints superior to those made with Vi-in. steel fasteners.

The Spectral Properties of Temporomandibular Joint Sounds

Journal of Dental Research, 1987
Spectral analyses were performed on sounds recorded from TMJ's that had previously been classified into different intracapsular categories, in an attempt to determine whether the inherent properties of these sounds were unique for each different disorder.

Mechanical properties of rock joints

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1985
Abstract Sliding on rock joints occurs in situ under various boundary conditions. A servo-controlled direct shear testing machine was constructed to simulate these boundary conditions in the laboratory. Thirty-one sandstone samples were tested with two varying loading paths: (a) constancy of the normal force and (b) restriction of the dilation.

Reality’s Joints I: Properties

1993
Abstract The idea that there are in some sense “natural joints” in the world goes back to Plato.1 What this idea seems to suggest is aptly expressed by David Lewis as follows: Among all the countless things and classes that there are, most are miscellaneous, gerrymandered, ill demarcated.

Dynamic Properties of the Human Temporomandibular Joint Disc

Journal of Dental Research, 2001
The cartilaginous intra-articular disc of the human temporomandibular joint shows clear anteroposterior variations in its morphology. However, anteroposterior variations in its tissue behavior have not been investigated thoroughly. To test the hypothesis that the mechanical properties of fresh human temporomandibular joint discs vary in ...

Dynamic Shear Properties of the Temporomandibular Joint Disc

Journal of Dental Research, 2003
Shear stress might be an important factor associated with fatigue failure and damage of the temporomandibular joint disc. Little information, however, is available on the dynamic behavior of the disc in shear. Since the disc is an anisotropic and viscoelastic structure, in the present study the dependency of the dynamic shear behavior on the direction

Viscoelastic Properties of Stiff Joints: A New Approach in Analyzing Joint Contracture

Bio-Medical Materials and Engineering, 1993
The purpose of this study was to ana1yze the joint stiffness after immobi1ization in a rat's lower extremity model. Rat knee joints were surgically immobilized in a full flexed position for periods of up to 7 weeks with or without intraarticular intervention.

Remarkable anti-wear properties of joint surfactant

Annals of Biomedical Engineering, 1995
A standard (four-ball) test has been used to study the anti-wear capabilities of ovine synovial fluid, the phospholipid extracted from it, a synthetic synovial fluid, and the phospholipid removed from the articular surface by a lipid solvent. Despite using speeds and loads that were "extreme" by engineering criteria, i.e., several orders of magnitude ...

Properties of Sensory Neurons Innervating Synovial Joints

Cells Tissues Organs, 2001
While it is clear that the TMJ joint has a sensory innervation like other synovial joints, there is little specific information about the function of the innervation of the TMJ. In order to provide a template upon which future studies might build, this article briefly reviews the function of sensory neurons in other synovial joints.
