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.

Calculation of contact stresses at contacts between conical bodies

Journal of Strain Analysis, 1972
A method for calculating the elastic-stress distribution in two axi-symmetrical conical bodies caused by frictionless contact between them is described. Finite-difference methods were used to solve the governing differential equations. Equilibrium and compatibility over the contacting surfaces was achieved by using the finite-difference solutions to ...

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.

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 ...

Contact Pressure and Stress Distribution

1995
A foundation is the interface between a structural load and the ground. The stress q applied by a structure to a foundation is often assumed to be uniform. The actual pressure then applied by the foundation to the soil is a reaction, called the contact pressure p and its distribution beneath the foundation may be far from uniform.

Contact stress in stranded cable

Experimental Mechanics, 1965
An experimental study of interstrand contact stresses existing in a stranded cable while it rests in its supporting clamp has been made using the stress-freezing photoelastic technique. Comparing the results with the Hertz contact-stress theory made it possible to establish criterion for suspension-clamp design.

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.

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

Contact Stress in a Gerotor Pump

Fluid Power Systems and Technology, 2003
The aim of the first part of this paper is to reach the optimum design parameters of a gear set when it works as part of an internal gear pump type gerotor. The performance of the gear teeth and the whole gear set are evaluated through analytical studies to obtain the maximum contact stress in gear teethe and the volumetric characteristics.
