TL;DR: In this paper, the failure modes of ring-stiffened cylinder models subjected to external hydrostatic pressure were investigated, including shell yielding, local shell buckling between ring stiffeners and overall buckling of the shell together with the stiffeners.

TL;DR: In this article, the failure modes were inserted in the quadratic Merchant-Rankine formula and the knockdown factors were empirically derived to best fit the actual collapse pressure, which can predict the ultimate strength of ring-stiffened cylinders more accurately and consistently than other codified rules (PD5500, GL, ABS, API).

TL;DR: In this paper, the failure behavior of a ring-stiffened cylinder subjected to external hydrostatic pressure is investigated. And the failure mode parameter obtained from the characteristic pressure such as interframe buckling pressure known as local buckling, overall buckling and yield pressure are also examined through the collected data and shows a good correlation.

TL;DR: According to comparison with certain RoRo collision incident data, the fully integrated version of the Belytschko–Tsay emerges as the most similar in terms of the damage criterion of analysis.

TL;DR: In this article, the impact responses of large-diameter, thin-walled steel stringer-stiffened cylinders subjected to low-velocity mass impact were investigated.
