FEM modeling of surface friction effect on scratch-induced deformation in polymers Conference Paper uri icon

abstract

  • Three-dimensional finite element method (FEM) parametric study was performed to investigate the effect of surface friction on scratch-induced deformation. By varying the post-yield behavior of the polymer substrate, the effect of surface friction on scratch depth and its correlation with the strain hardening slope is sought. The simulation results indicate that the onset of groove formation during the scratch process is strongly influenced by surface friction. Also, increase in strain hardening slope reduces the relative frictional effect on scratch depth.
