    Thickness Hub at the Small End, g0

    So, if I change the design to optional type as per sketch (8a), can it consider the total small end hub + shell thickness as g0? I believe also it is applicable for weldneck design, in a case that the neck thickness is higher than the shell thickness, can we consider the neck thickness as g0...

    Thickness Hub at the Small End, g0

    Dear Members, I am designing a Loose-Type Flange in accordance with ASME Section VIII Division 1, Mandatory Appendix 2, Figure 2-4, Sketch (4). I am in doubt whether we can consider the thickness of the shell + small end hub as g0 or it is only the thickness of the shell for g0. Please see...

    Fatigue Assessment - Elastic-Plastic Analysis SS316

    Hi, thank you for the reference. I can find the formula to calculate the Kcss and ncss, in the Para 2E.4.2.1. Do you think we can use that formula for fatigue assessment according to ASME VIII D2?

    Fatigue Assessment - Elastic-Plastic Analysis SS316

    Yes, I have that paper. But in that paper, they have selected Type 304 Annealed at 20degC for the value ncss and Kcss, to evaluate type 316 stainless steel. Do you think I can follow the same method to evaluate type 316SS?

    Fatigue Assessment - Elastic-Plastic Analysis SS316

    Dear Members, I am working on fatigue assessment according to ASME Section VIII Division 2 5.5.4, for Stainless Steel Type 316. During development of the material model, I realized that in Annex 3-D Table 3-D.2/2M does not provide the nCSS and KCSS for Type 316 material. Does anyone have...

    Mix System Unit in Design and Material System Unit

    Dear Members, I am designing a pressure vessel in accordance to ASME Section VIII Division 1. The unit system used in design is Metric system. Shall we mention the metric system unit also for material in General Arrangement Drawing (Bill of Material). For example, the material SA-516-70 shall...

    ASME VIII D2 Elastic Plastic Analysis

    IdanPV, What software do you use? What is the root cause of the error? Is that because the very high load, and the stress or strain result is beyond the material model curve?

    ASME VIII D2 Elastic Plastic Analysis

    IdanPV, Thank you for sharing the link. I have read your topic before. What would happen if the convergence is not achieved? Does the analysis get error or what?

    ASME VIII D2 Elastic Plastic Analysis

    Dear Community, I am working on the elastic plastic analysis of ASME Section VIII Division 2 Part 5. The material is SA-285 Gr. C, the Design Pressure is 0.3MPa at Design Temperature 200degC. I use the ANSYS 2024 R1 for the analysis. The material model with true stress-strain curve has been...
