###### Question details

A thin-walled cylindrical pressure vessel of initial diameter
D_{o} and initial thickness t_{o} is subjected to
both an internal pressure p and an axial for P. Derive an
expression for the maximum principal strain at instability for the
case in which circumferential stress component ^{'}_{1}
is greater than axial stress component ^{'}_{2}
