【 摘 要 】

Materials with soft & hard phases, showing excellent mechanical properties, are ubiquitous in nature. Herein this paper is proposed to investigate the frictional properties of materials with soft & hard phases by numerical simulation. The processes of a range of materials with soft & hard phases with different values of Young's modulus will be examined and their fictional mechanism will be discussed. It can be found that the maximum value of Mises stress is happened in the contact zone, and Mises stress gradually decrease with the distance from the contact zone increasing. The hard phase layer has the maximum Mises stress, and the soft phase layer has relatively small Mises stresses, which show the frictional property of materials with soft & hard phases.
