Circumferential strain in the cylindrical shell with hemispherical ends

(Strength of Materials – Er. R.K. Rajput)
In thin shells, the thickness of the section is generally very less and the are subjected to internal pressure which is the reason for the stress to be developed. The circumferential strain of the combined section can be calculated by the above formulae.
