Numerical solutions have been produced for the asymmetric instability of thin-walled circular cylindrical and truncated conical shells under external pressure. The solutions for the circular cylinder have shown that the assumed buckling configurations of Nash [l]2 and Kaminsky [2] were quite reasonable for fixed ends. Comparison was also made of the finite-element solution of conical shells with other analyses. From these calculations, it was shown that the numerical solutions were superior to the analytical ones, as the former could be readily applied to vessels of varying thickness or those subjected to unsymmetrical loading or with complex boundary conditions.

Buckling Failure

The prebuckled cylinder is a geometrical idealization of the actual buckled surface of an axially compressed circular cylinder. It is a polyhedral representation of the cylinder in which flat triangular surfaces are joined to form an undulated (corrugated) surface. Such surfaces have been generally regarded as failed forms of the cylinder; however, recent experimental investigations show that the prebuckled cylinder is remarkably more resistant to buckling failure under external pressure than the true cylinder. The prebuckled cylindrical (PC) shell can now be regarded as a new, unfailed structural form to resist external pressure.

Walled Cylinder

Safety analysis has been done for thick-walled circular cylinder under internal and external pressure using transition theory which is based on the concept of generalized principal Lebesgue strain measure. Results have been analyzed theoretically and discussed numerically. From the analysis, it can be concluded that circular cylinder made of functionally graded material is on the safer side of the design as compared to homogeneous cylinder with internal and external pressure, which leads to the idea of “stress saving” that minimizes the possibility of fracture of cylinder.
