Question:

For the case of a thin-walled tube under internal pressure, verify that the general solution for the hoop stress (8.4.3)will reduce to the strength of materials relation (see Appendix D, Section D.5)

As shown in Fig. D.18, under these conditions an axial stress and a hoop stress o, are generated at all

Note that because the vessel is thin, our analysis makes no distinction between inner, outer, and mean vessel

To determine the axial stress, we conduct an axial force balance of a sectioned half-vessel (similar to Fig.
