弹塑性三维各向异性分形表面的接触分析
Contact Analysis of Elastoplastic Three-Dimensional Anisotropic Fractal Surfaces
摘要
Abstract
A more useful generalization of the univariate scalar Weierstrass-Mandelbrot function is a weighted, random superposition of such ridge-like surfaces. The height function of a three-dimensional anisotropic fractal surface is deduced. The three-dimensional anisotropic fractal surface characterization is analyzed. Fractal dimension is extended to the three-dimensional universality. There are different relations between the mi-crocontact real area in elastic and fully plastic contact state and the truncated area of the microcontact. The theoretical analysis can be easily applied to account for anisotropic fractal surfaces and different material behaviors.关键词
