Abstract
In this paper, frictionbetween the Cube-Corner indenter and the sample surface of a Zr-based bulk metallic glass(BMG) was analyzed and discussed by the experimental method, the theoretical method and the finite element simulation. Linear residua are observed on the surfaceof the indenter for the first time, which gives the direct evidence that strong interaction processes exist between the indenter surface and the sample surface because of strong friction and local high contact press. A simplified model was developed to correct the penetration load with the consideration of friction.Effects of friction on the penetration load-depth curves, plastic flow, surfacedeformation and residual stress distribution of the sample with different friction coefficients were investigated by the finite element simulation.
