Hi rb1957, For the moments, I used a distributing coupling constraint at each end - control point as an RP at the centre, edges selected as surfaces. I applied the boundary conditions to the RP, along with the loads (bending moment and axial force). For axial force only, my Pcr is ~90%...

Hi FEA way, It's a linear eigenvalue buckling analysis that I'm looking at - trying to find the critical axial buckling load (Pcr) and critica end moments (Mcr). Initially, the box section beam is analysed to estimate the critical buckling loads (Pcr) with no end moments being applied...

Hi all, The beam is subjected to an axial load and end moments and I’m trying to find the critical end moment loads (Mcr) that cause buckling. I have a thin-walled hollow 2ply-composite beam (modelled with shell elements in Abaqus) that is simply supported (LHS is pinned, RHS is a roller...

Hi all, I’m looking at ASTM A694 F65 for a subsea flange. However the client spec specifies ISO 15590-3, and there is a difference in maximum Molybdenum content. 0.15 – 0.20% for ASTM A694 F65 0.1% for ISO 15590-3 I'm aware that Molybdenum primarily increases the corrosion resistance of...

Thanks MJCronin, SJones, LittleInch. DNVGL – ST – F101, section 5.3.2.6 states Possible beneficial strengthening effect of cladding on steel pipe shall not be taken into account in the characteristic resistance, unless the strengthening effect is documented. However, if the bond between CRA...

Hi there, I’m looking at a pipeline with wall thickness of 20mm and a 5mm corrosion-resistant alloy cladding. In terms of stress analysis and calculations, are there any guidelines or codes that state whether or not the 5mm cladding can be considered as part of the pipe wall thickness? Thanks
