Physiologic stress and tooth contact

Journal of Periodontal Research, 1969
This investigation was undertaken to study the relationship between physiologic data, such as pulse rate and stroke volume, to the occurrence of tooth contacts. The tooth contacts were monitored in the intercuspal (I.C.) position and lateral or eccentric to this position with the aid of radio‐transmitters constructed into dental bridgework as described

Contact Stress for Toroidal Drive

Journal of Mechanical Design, 2003
Considering the elastic deformation of the rotor and the periodic change of the mesh teeth pair number, the calculation equations of the load distribution for the toroidal drive are presented. Based on the equations, the formulas for calculation of the contact stresses among stator and worm are introduced.

Stress Hypotheses and material stresses in Hertzian contacts

Materialwissenschaft und Werkstofftechnik, 1986
AbstractUsing idealised assumptions, the stress condition in the semi infinite body of the Hertzian contact region can be calculated for various geometries as a function of the surface pressure (normal force), the friction (tangential force at the surface) and the residual stresses in the material.Equivalent stresses can be formed from the coordinate ...

Contact stresses in conical rollers

The Journal of Strain Analysis for Engineering Design, 2007
In this paper, the pure rolling contact stresses in conical rollers under normal loading are studied. The existing analytical expression for pure rolling contact pressure in uniform cross-section cylinders is modified to determine the contact area, the contact pressure, and its distribution in conical rollers under normal loading. The Hertzian contact

Stress intensity in viscoelastic contacts

Tribology Letters, 2000
Dynamic mechanical contacts with nanometer-to-micrometer dimensions are important in scanned probe microscopy, ultra-low load indentation, microelectromechanical systems, compact discs, etc. The response of these contacts is poorly understood if they involve adhesive viscoelastic materials, such as polymers and self-assembled monolayers.

Non Contacting Stress Monitoring

2008
Key input data for SIM calculations are the service stresses and the defect size. For some applications only the service stresses are required. For well designed structures this could be for stresses that arise during construction and early service life. For other situations it may be necessary to monitor crack/defect size and the local stress.

Residual stresses in rolling contact

Journal of Strain Analysis, 1969
The paper reports an experimental investigation into the residual strsses induced into cylndrical discs by the action of rolling-contact loads sufficiently high to cause some plastic deformation in the near-surface layers. A general method is first described for finding both circumferential and axial components of residual stress in cylindrical ...

Stresses and duration of cellular contact

Journal of Theoretical Biology, 1968
Abstract A significant factor in the bonding of cells is the relationship of elastic properties of the cells. With an assigned contact force, a cell which has a high modulus of elasticity develops high contact stresses of short duration. Cells with low moduli develop small stresses, and they have contacts of relatively long duration.
