WebSep 29, 2024 · The distribution of contact stress along the round edge is identified based on DMZ. Thus, determining the location of DMZ is extremely important. Three points (S 1, S 3, S 6) are used to define the geometrical model of this zone shown in Fig. 5 (a). It is found that materials slide out and separate due to shearing effect at the S 1 and S 3.

It captured the tension and bending stress fields in the disk that could not be determined with the SIE solution. It is computed by extracting the multi-axial components of the FEM stress along the path starting at the edge of contact. fiche regule
