Contact of Smooth Surfaces

Thermal Contact Resistance of Wavy Surfaces (RESEARCH NOTE)

In this paper, the method of determining thermal contact resistance of wavy surfaces is discussed exactly. For determining the thermal contact resistance of real contacts, a new method has been presented. In this method, assuming a regular sinusoidal surface profile, the real contact area in terms of applied forces has been determined. Then thermal contact resistance has been calculated. Testin...

Analysis of the Contact Area of Smooth and Rough Surfaces in Contact with Sphere Indenter Using Finite Element Method

This paper analyzes the contact area of the contact between a deformable rough surface (smooth and rough) and a hard smooth sphere indenter using finite element method. A method was introduced to generate a three dimensional rough surfaces using Computer Aided Design (CAD) software. The rough surface model was developed based on the surface measurement data, while the smooth surface model was g...

Projections of Piecewise-smooth Surfaces

In this paper we consider singularities of orthogonal projections of piecewisesmooth surfaces on planes. For a generic smooth surface, the apparent contour (outline, profile) of the surface associated with a projection onto a plane is the set of critical values of the projection. The singularities of apparent contours of smooth surfaces have been studied by several authors [1, 3, 8, 9, 10, 11, ...

Deformations of Smooth Toric Surfaces

For a complete, smooth toric variety Y , we describe the graded vector space T 1 Y . Furthermore, we show that smooth toric surfaces are unobstructed and that a smooth toric surface is rigid if and only if it is Fano. For a given toric surface we then construct homogeneous deformations by means of Minkowski decompositions of polyhedral subdivisions, compute their images under the Kodaira-Spence...
