Hello all,
In ASME fatigue screening methods, could someone please explain how to find the N[(KfbHc(3S))/2] in the eq. 5.19 ? Does it corresponds to N at [(KfbHc(3S))/2 ] in SN curve of the selected material?
Similarly for eq.5.20, whether ΔPN = 2PSas/[KfbHc(3S) ? or if ΔPN is the maximum...
Hello all,
we have a situation where the diameter of the header and nozzle are the same. So when we want to weld it together we arrive at a zone there will be atleast 3 welded joints join in. Could anyone tell what would be the joint efficency for such zone? is there any restriction for such...
Thanks again. I found the problem. For uniform thermal loading I get VM almost zero and some translation based on the thermal expansion co-eff. This method is the best for my application and thanks again to suggest this !
Hello Karachun,
I have tested 3-2-1 method and the results are quite satisfying. The ideal loading case for the problem I have explained above is applied pressure in all the cavities of both circuits along with the temperature gradient between them. I wanted to check if only with temperature...
Hello Karachun,
Thanks for your reply. Its indeed a great learning for me to learn about this method since I principally work with pressure vessels and always fix the bottom which is not reasonable. I will analyse this in depth.
For this model, I am only concerned about the thermal effects on...
Hello all,
I am relatively new and would like to clarify some doubt in analyzing thermal stresses in micro-channels of an heat exchanger.
I just consider only a small cross section of the entire model to simplify the model since my interest is only inside the channels.
In this case where...
Thanks a lot for your reply. I checked out your blog, unfortunately its in a language I dont understand. And google doesnt translate everything neither. But still I understand the concept to some extent. Thanks again!
Thanks Blas for your reply. But I am more interested in HEX elements and unfortunately mesh BODIES doesnt have this option and thats the reason I use HEXBODIES which I find very effective. My project contains some 50 plates with some cavities and my point of interest are the few plates in the...
Hello all,
I have two different bodies which has to be meshed with different sizes (to reduce the comp cost). But I want to have same mesh on the surface that is shared between the two bodies. I could achieve this by mesh control on the edges, but since these bodies has complex shapes, solid...
Hello all, I am new here and started working with Femap since 2 months. I am currently analyzing a pressure vessel which is connected to the flange through a nozzle. Since it is a standard flange I dont model flange but apply only the load (imposed by the weight of flange - nozzle loads in asme)...
