“…(4) and (5)). The Westergaard model also can be applied for the sliding contact of a rigid wavy surface with a viscoelastic halfspace (Menga et al, 2014). A modified model is used in this paper to predict the actual surface pressure and the pressure needed for the fingertip under the full contact condition.…”

a b s t r a c tTo control tactile friction, that is the friction between fingertip and counter-body, the role of surface texture is required to be unveiled and defined. In this research, an experimental approach is used based on measuring tactile friction for directional texture (grooved channel) with varying depths. For a reference surface, in this current case a polished surface from the same tool steel is compared. The experimental results are analyzed to explain the observed skin friction behavior as a function of surface texture parameters, sliding direction and applied normal load. Sliding parallel to the groove length shows greater values in COF than sliding perpendicular to the groove direction. Furthermore, parallel sliding reveals a higher dependency of COF on the depth of the grooved channel texture than perpendicular sliding. Application of the two term friction model suggests that the adhesion component of friction has greater impact on parallel than perpendicular sliding direction. According to the observations, grooved channels are well suited to control skin friction in direction dependent sliding, for moderately loaded contact situations. This experimental research contributes to the haptic perception related research, and to the development of other direction-dependent surface structures for touch.

“…The growing interest in polymeric materials, strongly supported by industrial demands, has boosted the scientific effort in such field of materials. The demanding problem of an accurate modelling of the contact behavior has been addressed by analytical approaches [1][2][3][4][5][6][7], numerical sophisticated simulations [8][9][10][11][12][13][14][15] and experimental investigations [16][17][18][19][20]. One of the most common assumptions in contact mechanics is that the contact bodies can be well represented by semi-infinite solids.…”

“…Westergaard developed a model to estimate the contact ratio between an elastic half-space and rigid wavy surface with spacing (k) and amplitude (depth or height of the structures) [36]. Study found that the Westergaard model also can be applied for a viscoelastic half-space including skin sliding on a rigid wavy surface [11,12,16,22,26,29]. A modified contact model was proposed in the previous study to predict the contact ratio by calculating the average contact pressure ( p) and the pressure needed for the fingertip under the full contact condition…”

Surface texture is important for contact mechanical and tribological phenomena such as the contact area and friction. In this research, three different types of geometrical microstructures were designed and fabricated by pulsed laser surface texturing as semi-symmetric (grooved channel), asymmetric fractal (Hilbert curve), and symmetric patterns (grid). A conventionally finished surface as a reference sample from the same stainless steel sheet material was compared. From the experimental approach, a multiaxis force/torque transducer was used to investigate the functionality of surface texture based on measuring the tactile friction in three different sliding directions: perpendicular, parallel, and 45°to the textures. According to the dynamic friction measurements, the grid texture was indeed orientation independent. The other samples showed orientation-dependent frictional behavior, especially the grooved channel texture and reference sample. Furthermore, an analytical approach was applied to estimate the values of the friction coefficient by the pressure distribution method. From both the experimental and analytical approaches, the grid pattern was validated to be the optimal texture design in the concern of friction reduction and orientation-independent behavior.
