WebVarious stress–strain curves can be realized by varying the η-λ relationship in Table 1, e.g., keeping λ the same but reducing η accordingly. With this approach, another three types of stress–strain behaviors are generated here, e.g., Case 2, Case 3 and Case 4, as shown in Fig. 3. As can be seen, the ductile behavior of Case 1 is the ... WebBased on fracture mechanics theory, a finite element method was used to determine the stress intensity factors of the inclined crack on the inner surface of the pipe under axial compression load and external pressure. The effects of different influencing factors on the stress intensity factor along the crack front considering crack closure were systematically …

WebJan 19, 2016 · Fig. 4—In an inclined well, stress magnitudes can be determined simply from knowledge of the orientation of wellbore breakouts. In this case, given the magnitudes of S v and S Hmin and the orientation of S Hmax, it is possible to constrain the magnitude of the maximum stress.In addition, it is possible to constrain in-situ strength using the breakout … WebGeometrical interpretation of the deviatoric stress invariants in principal stress space.

WebMay 2, 2005 · An analytical method is presented for the calculation of the load carrying capacity of two-dimensional asymmetric rock wedges when the loading on the joint faces is non symmetric, such as the case of an asymmetric wedge formed in the roof of a circular tunnel in an inclined stress field. The pull out force that causes yield at one of the joint ...
