    Calculation of pressure-temperature limites for stainless steel

    Hello everyone Im performing the calculations for stainless steel pressure vessel. My question is., how can i find a procedure for P-T limites for stainless steel. Appendix G addressed and presented the calculations for SA-508. Thank you in advance

    FEM modeling of Body flange

    Thank you for reply I want to check bearing stresses in contact area between bolt and flange face. It is body flange so i need to check theses stresses. Furthermore there are three stress categories (Sh, Sr,...) so i can check these stress with allowable values in appendix.

    FEM modeling of Body flange

    Hello everyone I am modeling a body flange using abaqus, as you know according to appendix XI there is rules for evaluation of bolted flange connection. My question is, if we want to make this evaluation using FEM, is there any rules or method to be implemented? Or can we use XI criteria?

    Stress categories

    Thank you for reply So it say that if bending moment in edge of the head is required to maintain pb in middle of the head in acceptable range, bending stress is classified as pb. How we could find that bending moment in edge is maintaining the pb in middle in range?

    Stress categories

    I do not understand what the limit of bending stress in middle of flat plate is!!! If you have any source to introduce, I will appreciate it.

    Stress categories

    Thank you for reply. I didn't get the meaning. Would you please explain it more. It isn't clear what the bending stress in middle is Thank you in advance.

    Stress categories

    Hello everyone Does any one knows the meaning of this sentence in asme sec iii, nb. IT IS a note in stress categories section. If the bending moment at the edge is required to maintain the bending stress in middle to acceptable limits, the edge bending is classified as pb otherwise is Q. Thank...

    Response Spectrum in PV-Elite

    I am designing a vertical pressure vessel using Pv-Elite, when you entering the input data for seismic analyses is it true to enter the values of Acceleration as a factor of G? , for example for the acceleration of 30 m2/s we should enter the 3.27 in input table instead of 30. thank you in advance.

    ASME III, Division 1 - Plastic Analysis (FEA) using Ansys 13.0

    You can choose either ANSYS or other valid finite element software... If you want to see the result contours, the default form is shown base on Von Mises, but you can choose your criteria,,,,and don't forget to normalized the stress result through the thickness.

    Modeling of buckling

    Im responsible for design of pressure vessels, in a case of modeling of support skirt and possibility of buckling, I was wondering if it is possible to perform a buckling analyses in conjuction with seismic analyses, which performed using response spectrum. thankyou in advance.
