It prevents interference between the source and target faces during loading but allows them to move away from each other to form gaps. For thermal studies, this option is available with the Thermal Resistance contact type. For nonlinear studies, a surface to surface contact option is available ...
A method is presented whereby the pressures, which are generated at the contact surfaces of two axisymmetrical components assembled together with an interference fit, can be determined. The approach of this method is to set up a series of influence coefficients for discrete matching nodal positions...

Elastic contact between a rigid plane and a halfspace whose surface height is described by a bandwidth-limited Fourier series is considered. The surface normal displacements and contact pressures are found by a numerical technique that exploits the structure of the Fast Fourier Transform (FFT) and ...

The asperity interference\(\delta \)17of a single asperity is determined by the fractal surface profile, and is equal to the peak-to-valley amplitude: $$\delta \,=\,2{G}^{(D-1)}{(\mathrm{ln}\gamma )}^{1/2}{(2r^{\prime} )}^{(2-D)}$$ ...
beam delivery unit that superimposes a pair of laser beams onto a moving surface for producing an interference pattern having straight-line fringes on it and a light collector assembly that captures radiation reflected from different parts along the surface and directs the radiation to a detector....
The second aspect is how to describe truly the friction phenomenon on the contact surface. The last aspect is the non-linearities of material behaviors and geometric deformation. The importance of the contact phenomena has brought about extensive research work over the years. At present, there are...
