Cylindrical stress field

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 WebJul 12, 2024 · σt1 = Circumferential or hoop stress for the material of the cylindrical shell.
