Abstract
Experimental tests were carried out to
destruction on three ring-stiffened thin-walled
circular conical shells under
uniform external pressure. The
experiments have shown that for even
small imperfections in the geometry of
these vessels, there was a considerable
loss of buckling resistance, especially
for the less slender vessels.
A semi-empirical design chart is provided, which enables a plastic reduction factor to be determined; this plastic reduction factor can be used in conjunction with a finite element solution for perfect vessels, so that the inelastic buckling pressures of these imperfect vessels can be calculated. purchase the full-text of this paper (price £20)
