Dear All, I'm trying to evaluate a method to design rectangular flange "according" to ASME PCC-1 and ASME VIII Div.2 What value should I use for pre-load the bolts in Service Criteria and Global Criteria for Elastic-Plastic Stress Analysis ? I'm trying: W = max(Wo;Wgs) Wb = 1.5W (bolt...

Another concept applied to BFJ is Service Criteria. I suppose If I apply factor on pre-tension I will satisfy the Global and Local Criteria (In cases that bolts do not go over ultimate). But I think that the service criteria may not have a satisfactory (consistent) results, like flange rotation...

Dear All I'm here again with other question about Elastic-Plastic Analysis. How should I apply LRFD concepts to bolt pretension for an analysis of bolted joint? Since I will apply the required factored loads to internal pressure... I think I will apply the same factored loads (for internal...

Take a look at ASME VIII Divison 2 Annex 3.D.

Thank you Victor and TGS4 @TGS4 I was thinking of bi-linear to minimize the computing time. But I will continue with the full curve Best regards

Dear All I am running an elastic-plastic analysis for a pressure vessel according to ASME VIII Div.2 - item 5.2.4 and I pretend to use a bilinear material model. But I am in troubling about the value of the Tangent Modulus that I should use. I plotted the stressxstrain curve of the SA-516 70...

Dear Have you read ASME VIII Div.1 Mandatory Appendix 1 - item 1.7 LARGE OPENINGS IN CYLINDRICAL AND CONICAL SHELLS?

Thanks TGS4

Thank you RaymondN, We are considering all requirements for offshore installation.

Thank you all!!

Dear All I'm engaged in a study about bolted flange joint and I need find the flange rotation. Someone knows how I can find the rotation by an analytical calculation? (book, code, article...) At moment I'm using just FEA. Thanks in advance

Tigny, Thank you! I will check some FPSO regulations

inammanj123 I guess not, since we can not model a tangentinal nozzle attached to head. (I just tried to model, but I didn't get it)

As TGS4 replied, you need FEA. Since the WRC 107/297 does not find the actual stress values for your case.

Thank you for your reply SntMan
