Contact stress of disk on edge

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.
