Abstract:
To predict contact and wear of metal surface microscopically,a metal surface wear simulation method based on the theory of elastic-plastic contact is proposed and established in this paper.The numerical simulation model is verified by comparing the calculation results and experimental results.Micro-surface morphology of Q235A and 45
# are simulated by using the adaptive correlation function.The numerical amount of wear is calculated under different external loads.The wear process and properties of metal surface are analyzed with considering the relationship among the wear,toughness and the distance of the wear surface and times.The present study provides a new way for the theoretical calculation of the wear process for the metal surface.
