Witryna8 mar 2024 · With a pop-in event, a P – h curve deviated from the Hertzian fit, and the sample plastically deformed. Here, the onset load of plastic deformation Pc1 is defined as P value where h value in the P – h curve deviated 1 nm from the Hertzian fit. Based on the Hertzian theory, shear stress beneath the indenter τmax can be obtained by, … WitrynaThe fitting parameter S/K 2/3 found is 31.28 (Pa) 1/3 for Fig. 10 (a) and 31.33 (Pa) 1/3 for Fig. 10 (b). This agreement and the good fittings imply that, within the range of normal loads employed in Fig. 10, the contact between the indenter and the PDMS coating obeys the Hertz theory, and the friction force is proportional to the contact area.
