The stress analysis of eccentric-wear casing
Fig. 1. As shown in Fig.1, the outer ring is the casing, and the middle is the drill pipe. The unworn part of the casing is going to be analyzed. The diameter of the drill pipe is 127mm. the outer diameter of the casing is 177.8mm, and the thickness of the casing is 13.72mm. The … Continue reading The stress analysis of eccentric-wear casing
