WebThe analysis of a thin-walled internally-pressurised cylindrical vessel is similar to that of the spherical vessel. The main difference is that the cylinder has three different principal stress values, the circumferential stress, the radial stress, and the longitudinal stress l, which acts in the direction of the cylinder axis, Fig. 7.3.9. WebFeb 28, 2016 · The standard cylindrical coordinate basis should have a Minkwoski metric, since we don't really have curvature in this case. The only difference is then a 1 / r factor in the ϕ component. Therefore, in order to be consistent, you need to replace A 2 → A ϕ r. Then, you will see that F 02 = E ϕ r, which, again, is consistent with your metric. Share
