AB  - Ripple deformations induced by friction on polymeric materials have negative 
      effects on the entire stability of operating machineries. These deformations are 
      formed as a response to contacting mechanics, caused by the intrinsic mechanical 
      properties. High-density polyethylene (HDPE) with varying silicon nitride 
      (Si(3)N(4)) contents is used to investigate different ripple deformation 
      responses by conducting single-asperity scratch tests. The relationship between 
      the intrinsic mechanical properties and the ripple deformations caused by filler 
      modifications is analyzed in this paper. The results show the coupling of the 
      inherent mechanical properties, and the stick-slip motion of HDPE creates ripple 
      deformations during scratching. The addition of the Si(3)N(4) filler changes the 
      frictional response; the filler weakens the ripples and almost smoothens the 
      scratch, particularly at 4 wt.%, but the continued increase in the Si(3)N(4) 
      content produces noticeable ripples and fluctuations. These notable differences 
      can be attributed to the yield and post-yield responses; the high yield stress 
      and strain-hardening at 4 wt.% provide good friction resistance and stress 
      distribution, thus a smooth scratch is observed. In contrast, increasing the 
      filler content weakens both the yield and post-yield responses, leading to 
      deformation. The results herein reveal the mechanism behind the initial ripple 
      deformation, thus providing fundamental insights into universally derived 
      friction-induced ripples.
