    Exact physical significance of Sec VIII Div.2 Annexure 5D

    Hi, NRP99, thanks for your response. I still have the question how can I calculate Sa if I want to aplly the assesment of part 5.5.3 from ASME VIII div 2? Thanks

    Exact physical significance of Sec VIII Div.2 Annexure 5D

    Hi, I have 2 simple questions 1) ΔSpk is the equivalent von misses stress that I can take from my simulation before the stress linearization? 2) Sa (alternating stress amplitude) isn't Salt ? If the answer is no, the way to calculate Sa from Part 5 is calculate the screening criteria factor...

    Calculate Pb (bending stress) linearization

    Yes, I am doing exactly what the code says, because I am doing an excel tool to linearized stresses, But I compared the results of bending stress using ansys with the integral at the code, and are very different. Also I saw a post from you TGS4: "When I said that ANSYS linearization doesn't...

    Calculate Pb (bending stress) linearization

    Hi, I made the model in ANSYS and the linearization bending results are not the same. I think this is because Ansys doesn't with the ASME Code Linearization. But Do you know what code ansys uses?

    Calculate Pb (bending stress) linearization

    Hi again, I used the formule σcb=(t2/6)*Σ1n(σc[i]+σc[i-1])/2*(x[i]+x[i-1]-t)/2*(x[i]-x[i-1]), but what equation I should used for the node 0 and the node n?

    Calculate Pb (bending stress) linearization

    Yes, they say there is only one value for Pb, but there is one value for Pm too. So, how can I get the graphic where Pb+Pm is not constant, like the image.

    Calculate Pb (bending stress) linearization

    ok, I am confuse then... Because, the engineers of PVENG make graphics showing the SCL line at the x axis and for the y axis they show the Pm+Pb stress, for each node of the line, like this image. So, what means Pm+Pb in the graphic if there is just one Pb...

    Calculate Pb (bending stress) linearization

    Hi, I have use the σcb=(t2/6)*Σ1n(σc[i]+σc[i-1])/2*(x[i]+x[i-1]-t)/2*(x[i]-x[i-1]) but that is for the final result, I need the bending stress for each node, and for node 1 the bending stress is 0 using that formule because X(i) is 0. I think I have to use the trapezoidal method but I don't...

    Calculate Pb (bending stress) linearization

    Hi again, I forgot explain that my model was axysimetric, The form to calculate membrane and bending stress is the same?

    Calculate Pb (bending stress) linearization

    Oh, TGS4 sorry I didn't mean that I wanted you to solve the problem. I just wanna know that I want to get is possible. And I put my values to give you an idea.

    Calculate Pb (bending stress) linearization

    Hi, Prex and TGS4, Thanks for your responses. I had a mistake. t=0.02 and dx=0.0018, I have 11 nodes. My values are: NOEUD SIXX SIYY SIZZ SIXY SIXZ SIYZ N1 -9.35135774870612E+03 1.44904368707696E+04...

    Calculate Pb (bending stress) linearization

    Thanks for your response TGS4, but I don't understand how to integrate that values, If the thickness is 0.02 and the SCL measures the same, but the distance between nodes is 0.018, then t=0.02 and X=0.018?

    Calculate Pb (bending stress) linearization

    thread292-95338 Hi, I need some help. I have to calculate the stress bending tensor in a SCL (stress classification line), I have the stress tensor at the SCL but now I have to apply this: σib=(∫σi(x-t/2)dx)/(t2/6) How can I do this?. I have 6 σi, the distance between Node 1 and Node 2 is...
