Instability of Thin Pipes Encased in Oval Rigid Cavity

Abstract

A new model for predicting the buckling pressure of thin circular pipes encased in rigid oval host pipes is presented. This paper also includes experimental work that has been conducted to verify the new model. The results of the experimental work are compared with the proposed model and other analytical models. Conclusions drawn out of this comparison study show that the proposed model provides a good agreement with experimental results.
