Ultrasonic Measurement of Contact Pressures in Automotive Component Contacts
SAE Technical Paper Series, 2006<div class="htmlview paragraph">The measurement of pressure at a contact in engine parts is important, because it is frequently contact stresses that lead to failure by seizure, wear, or fatigue. Whilst an interface might appear smooth on a macro-scale, it consists of regions of asperity contact and air gaps on a micro-scale. The reflection of an

IEE Colloquium Recent Advances in Power Devices, 1999
Some of the design considerations for the implementation of a bondless, pressure contacted IGBT are outlined. Whilst the electrical performance of each type of device is similar, some differences in the mechanical and thermal properties of pressure contacted devices to those exhibited by substrate mounted devices are highlighted.

Pressure contacts to Bi2212 whiskers
Superconductor Science and Technology, 1997Eight electrical silver contacts were attached to very small and thin orthorhombic Bi2212 single-crystal whiskers by the application of pressure in a small cell developed especially for this purpose. No heating treatment of the sample and the contacts was necessary; thus, diffusion of the contact material into the sample was avoided. Four contacts were

Contact Pressure of Quadrupedal Animals
Volume 5: 19th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2003In this study we determine the pressure on the central area of each of the weight bearing pads of the paws of dogs at the walk. Pressure signal data from stance phase during walking were analyzed. Within paws, there were significant pressure differences among pads on both fore and hind limbs. The coefficient of restitution, the embedding dimension, and

The Contact Patch Test for Linear Contact Pressure Distributions in 2D Frictionless Contact
2011It is well known that the classical one-pass node-to-segment algorithms for the enforcement of contact constraints fail the contact patch test. The situation is particularly critical when using the penalty method. In a recent study, the authors proposed a modified one-pass node-to-segment algorithm able to pass the contact patch test also in ...

Joint Contact Area and Pressure
1991During the later half of the past decade a considerable amount of information on the biomechanics of the human wrist has been uncovered by measuring the contact areas and pressures in cadaver wrists in a variety of normal, simulated post-traumatic, and surgically treated conditions.

Contact techniques in ocular biometry, influences of intraocular pressure and probe contact pressure
1988In an experimental study the influence of the intraocular pressure and the contact pressure of the transducer to the cornea is examined. The aim was to evaluate some of the advantages and disadvantages of applanation methods for ultrasound oculometrie.
