Hi All, I am looking for a formula to describe the stress in the centre of a circular plate, stiffened with a small pipe. Something like added section. Roark formula 9(a), from table 11.2 is quite good if i compare the results with FEA, but that is just a flat circular plate.(without the...

Hi! Thank you for your replies. First of all. the results shown is a section view of the results. My first intention was not to give the full report about how I modelled this shaft cover, but since you are both asking for it... Solid mesh, very, very small elements (1x1x1mm) Why solid...

Hi. I am trying to calculate a flat shaft cover, mounted with several bolts. These are the dimensions (in metric system): shaftØ140mm cover outer D=160mm thickness=12mm bolt= M16 (3x), hole Ø18mm, pretension bolts is 640*70%MPa. PCD=Ø110mm First I tried doing this with the use of Roark...

hi all, While I was looking for information I walked into this thread: thread727-211759 It is about recognizing and analysing peak stresses. Some say that you can find general statements in every report where it appears that the analyst has no clue what is going on. It is nice to read through...

I was actually looking for the actual formula which is used by femap to calculate von mises. I looked in studybooks and tried already a lot, without any success, that is the reason i asked it hear.. :)

Hi All, I am using femap and i have a question regarding outputvector stresses. 1) Is there a location where i can read about the differences in outputvectors 60010-60031 "normal", "shear", "principle" and with what formula the solid von mises stress is calculated? 2) I am loading a block in...

Hi Rb1957. I have the template already. But I want Femap to automatic start with it when I open Femap. I know it is possible, because i have done it before...

Hi al! I am using Femap and finally i have a file with al my preferences, materials and properties. Is there a way to set this file as a template?? Thanks

Thank you RB1957! Solid elements is indeed an option. How would you suggest to connect the multiple -30- thick plates with eachother? RBE2? I know that getting proper results is quite tricky. That's why I asked the question overhere ;) Also Thanks NRP99. If you are talking about the ratio for...

Hello, Sometimes I am struggling with element sizes of finite element models, especially when the plate thicknesses vary a lot. As an example i added a attachment. A plate, thickness 60mm, is welded to a pipe (diameter=200mm, wall thickness is 12mm). I chose element size 15mm, because of...
