Abstract: | An algorithm for calculating the force of friction between a fractal rough solid surface and a model elastomer with arbitrary
linear rheological properties has been developed based on the method of dimensionality reduction with application of a hierarchically
organized memory. Using this method, it is possible to calculate the friction force between an elastomer and a solid surface
with experimentally determined topography, taking into account both the broad spectrum of wave vectors (ranging from nanometers
to centimeters) for real surfaces and the wide range of relaxation times (from nanoseconds to seconds). |
