The article deals with the creation of a mathematical model that can be applied in the testing of various materials.
Static and kinetic coefficient of friction If we consider an example such that we have only the case of two materials, where one material is a base that is fixed and the other test material is placed on it, which is shown in Fig. 1.
Fixed material Testing material F FN FR Fig. 1 Two materials with considered forces In Fig. 2 shows the dependence of the resistance force taking into account the static and kinetic coefficient of friction.

Finite Element Simulation of Abrasive Wear and Study of Wear Resistance of Material Fan Yujin1, a, Li Zhekun1, Han Teng1, Wang Weida1 1Faculty of mechanical and electrical engineering, kunming university of science and technology, kunming,650050,china afanyujinkmust@163.com Keywords: abrasive wear; wear resistance; surface deformation; finite element analysis; numerical simulation Abstract.
Though the development of material science, surface physics and chemistry, surface analyzing and testing technology greatly contributed to further research of friction and wear, however, abrasive wear was complex process and difficult to describe simply[5-6].
There were three metallic materials mentioned in the paper, 35 quenched and tempered steel, 45 normalized steel and 35SiMn quenched and tempered steel, material elasticity modulus E=206GPa, Poisson ν =0.3, the friction coeffient of particle and material surface μ=0.15, Figure 1 was the stress-strain curve of metal material, the mechanical parameters of materials were as follow. 35 quenched and tempered steel: yield stress σs=295MPa, tangent modulus Ctm=825MPa, tensile strength σb=550MPa, reduction of area ψ=0.38, actual tensile strength σbt=1052MPa. 45 normalized steel: yield stress σs=295MPa, tangent modulus Ctm=1070MPa, tensile strength σb=590MPa, reduction of area ψ=0.38, actual tensile strength σbt=952MPa. 35SiMn quenched and tempered steel: yield stress σs=510MPa, tangent modulus Ctm=1120MPa, tensile strength σb=785MPa, reduction of area ψ=0.45, actual tensile strength σbt=1427MPa.
