Stiffness of contacts between rough surfaces.
The effect of self-affine roughness on solid contact is examined with molecular dynamics and continuum calculations. The contact area and normal stiffness rise linearly with the applied load, and the load rises exponentially with decreasing separation between surfaces. Results for a wide range of roughness, system size, and Poisson ratio can be collapsed using Persson's contact theory for conti...
متن کاملElliptic-Curves Cryptography on High-Dimensional Surfaces
We discuss the use of elliptic curves in cryptography on high-dimensional surfaces. In particular, instead of a Diffie-Hellman key exchange protocol written in the form of a bi-dimensional row, where the elements are made up with 256 bits, we propose a key exchange protocol given in a matrix form, with four independent entries each of them constructed with 64 bits. Apart from the great advantag...
متن کاملImproved Blends between Primitive Surfaces
By applying results on canal surfaces, we study exact rational parametrizations of fixed radius rolling ball blends of pairs of natural quadrics. We classify all configurations where this kind of rational parametrization is possible, and describe a general algorithm for parametrizing fixed radius rolling ball blends. The algorithm is then applied to parametrize the fixed radius rolling ball ble...
متن کاملNormal and tangential compliances of interface of rough surfaces with contacts of elliptic shape
The incremental compliances, normal and tangential, of an interface between rough surfaces are considered. Contacts are assumed to be elliptic – the shape of Hertzian contacts between any two locally smooth asperities. The ellipses may have diverse eccentricities and random or non-random orientation distribution; in the latter case, the tangential compliance is anisotropic. It is found that the...
متن کاملIn-situ Measurement of Elastic Velocity Contrast between MgSiO3 Enstatite Polymorphs at High Pressure
Introduction Orthopyroxene is an important mineralogical constituent of petrological models of the Earth’s upper mantle. Therefore, the reconstructive (or first-order) phase transformation between orthoenstatite (OEN, orthorhombic symmetry, space group Pbca) and highpressure clinoenstatite (HP-CEN, monoclinic symmetry, space group C2/c) is of great interest for geophysical applications. In part...
