Buckling of Thin Shells Under External Pressure
TLDR
In this article, the buckling value of the external pressure acting on thin cylindrical shells has been derived on the basis of various linear bending theories for certain ranges of shell shapes.Abstract:
Expressions for the buckling value of the external pressure acting on thin cylindrical shells have earlier been derived on the basis of various linear bending theories. For certain ranges of shell ...read more

Simplified theory for the behaviour of buried flexible cylinders under the influence of uniform hoop compression
Ian D. Moore,John R. Booker +1 more
TL;DR: In this paper, the elastic behavior of a long flexible cylinder buried in an infinite elastic medium and acted on by uniform hoop compressions is examined, and a simplified solution is obtained, which can be used to accurately and efficiently determine the cylinder response.
