초록

This study presents a theoretical solution of elastic critical buckling load of infinitely long pipelines with non-uniform thickness under external pressure. The solution is derived with an assumption that a cylindrical shell under external pressure can be considered as a simple ring. The eigenfunctions are derived to obtain the critical buckling load for a ring structure with two thickness-reduced regeions. The finite element analysis is performed to verify the theoretical solutions.
