I have a calculation on a conical section under combined loading, including earthquake. The calc is to PD5500 Appendix B, and PD5500 Annex A (which is a compressive/Buckling check), and PD5500 Section3, covering reinforcement at the small and large ends. The Internal Pressure is less than 1bar...
I have a rectangular vessel, which is stiffened such that the largest area of unstiffened flat side is not overstressed in bending, and the deflections calculated using Roark are deemed to be acceptable. The stiffeners have been designed and are satisfactory. (I think the stress limits are from...
When cold forming an 8mm plate, i.e. bending it to effectively form an 90degree angle, the strain on the outer fibres approaches 20%.
PV codes appear to restrict this strain to 3% or 5% but I have a feeling that this is for pressure parts such as dished ends and the like.
The cold formed...
