A plastic mechanism formulation for the general instability of ring- stiffened cylinders under pressure-dominated loadings
This paper presents a rigid-plastic mechanism approach to investigating the collapse behaviour of ring-stiffened cylinders failing in the general instability mode under pressure-dominated loadings. Experimental data from various sources are used to correlate with the results of the analysis. The influence of initial geometric imperfections on the collapse behaviour is also discussed in detail.
