Hi Pingen, All the above are valid answers and, as you said it yourself, cover the subject way deeper than you need. Going back to the core of your question: for simple applications it is reasonable to consider that you don't need to model the weld, as long as you probe the results in the...

Hi, I am looking for a case hardening steel equivalent to DIN 14NiCr18; it has to have a Yield Strength of 900MPa and it has to be able to take surface cementation up to 65HRc. Obviously, if there is a steel out there that has this hardness down to the core, it will also do well. 14NiCr18...

Thank you very much. dulmant

Thanks ijzer, Where did you get this? Any refference? dulmant

Hi, Does anybody knows what are the ultimate and the yield strength values for Steel DIN CK75 (and CK67), used for DIN 2093 disc washers? Thank you, dulmant

Hello BreadTruck, First of all, it can be argued that F= Wxf is a too simple way to calculate the pull force of the chain. You must consider the weight of the chain itself, as well as its tensioning preload and the efficiency of the chain mounting system. Then you have to take into account the...

CoryPad, This 0,8xp gave me a lot of truble; I don't know if you remember but I brought this up a while ago and you were kind enough to point me in the right direction. However, at the time you left this detail out and my preliminary calculations didn't consider it. Later, when I got the...

Dear All, First of all I would like to thank everybody that answered my previous thread (31st of January). I need now to take this subject further, as I still didn't get to any conclusive results. Apparently there is no theoretical way to relate the percentage of load the first thread of a...

Dear all, I am looking for a "table" that could relate the screwing depth to the bolt/nut materials (or property class). I encountered only very general observations and "good-practice" advises, but nothing that would tell me, for example, what is the screwing depth...
