Sorry, my latest supplement (7) of BVPC only arrives to 2604.
I'm doing a comparison between Div2 and EN13445 as per creep design is concerned. I'll ask our supplier if new supplements are available, but in the meanwhile I wonder if you could summarize the 2605 topics.
Thanks

Thank you so much TGS4 and prex, now it makes much more science. I remember I read in the ASME (probably old DIV2 Appendix 4) that local membrane are actually secondary stresses but treated as primary, but without your help I probably wouldn't have sorted it out.
As per the limit Load, is...
I have a question about the upper limit for a hydraulic test pressure according to Sect VIII Div 2, 8.2.1.
According to paragraph e), which refers to 4.1.6.2.a, the test pressure shall not exceed that value which results in the following equivalent stress limits:
Pm<=0.95 SY
and
Pm+Pb<=1.43 SY...
jte,
I understand your concern. Just some explanations.
a) 70 and 50 psi are two sample values, used just for the sample, although I actually deal with vessel in that pressure range.
b) I cannot disclose further details, but the vessel has some shape discontinuities that cannot be handled by...
TGS4,
thanks for your reply. As I said in the opening post, I read all the 4.1.5.2 definitions, before posting. As you correctly pointed out, a good part "n-1" knowledge is requested before going to part "n".
Nevertheless, still was not sure about the correct answer. Please do not take my word...
Hi,
I have a simple but fundamental question about the Limit Load Analysis according to 2007 Div.2 part 5, and on the concepts of LFRD approach.
Let's suppose I have to design a vessel with the following data:
Design Pressure: 70psi
Operating Pressure 50psi
According to the assessment...
Hi Greg,
usually the models are linear, lot's of load cases, big number of dof (>300'000). Windows XP cannot address more than 3GB for a single process, afaik, even though it can handle up to 4GB of ram memory. Sometimes I do some non linear (plasticity and contact).
In those cases it happens to...
I've been asked to write down a specification in order to buy a new high end workstation for my company. This pc will be used mainly for FEM Modeling (Femap) and solving (NeNastran).
Which is the best hardware configuration I should ask for?
I'm puzzled about CPU (Intel Xeon or AMD), and...
You are not going to find out the surface convection coefficient in the material database, as it depends on the boundary conditions. The same steel part will have very different coefficients in different conditions: it will vay with the heat exchanging medium (water, air), and its speed and...
i've tried several programs for this tasks, the best i found out was Engauge Digitizer
http://digitizer.sourceforge.net
it's also free, opensource, available for win32 and linux.
Anyway it's worth a try
Hope that helps

Usually i workout this situation switching on the curves visualization, setting an appropriate curve color (i.e. black).
Of course this applies only if you have a geometry associated!
