Hi guys, I would appreciatie some guidance for a good 2nd hand workstation purely for SW mondeling (modeling is single thread mostly, right?). After some research I would say the E3-1240 is the better choice, do you agree? Thanks and all the best [thumbsup2]

Hi Guys, hope you're all well So, in ND testing of cracks in metallic materials most seems to be with (high freq.) AC current powered primary coils and eddy current induced secondary fields (which are probed one way or another). But why is this done with AC since DC is also suitable for...

Hi guys, I know thtat cold working produces more dislocations that 'impede slip and thus increase strength' but i'm kind of puzzled to what exactly happens in the lattice. In this context I also read about 'forest dislocations' but I'm srugling to get a clear comprehension on this, hope some...

Thanks Cory [love]

I didn't land the job, but due to the helpfull feedback and study on my part I'm better prepared for round 2! thanks and love [love]

"unless there are some specific area, and specific materials where make this term being a specific meaning, it indicates the max temeprature at which a material can be used in applications/engineering. Strength can be decreased to the extend that it is still meet the spec. For example, suppose a...

Hi guys, hope you're all on your game [love] I was wondering why under tensile the shear plane is @45 degrees in regard to the applied load. (is it exactly @45 degrees btw?) Is this because: a)the shear is at max under this orientation or b)because the plane stacking is non-dense at this...

Thanks arunmrao. The term kind is kind of misleading I think since it sort of implies that properties are stable up to that temp (which clearly is not the case, for instance tensile strenght reduction). Is this directly related to not upsetting the original lattice (previous heat treatments /...

Hi guys, hope you're all well. What is the difference between the term "ploymers" and "elastomers"? I'm somewhat confused? [love]

Hi guys, hope all is dandy. What exactly does "max. service temp" mean for a material? It seems pretty straightforward but I'm not sure. [love]

Hi guys, thanks a lot for your pointers. I'm studying these among others in detail. quiztime: - what is meant when they speak of "full lug". Does this mean the lugs are full thickness of the valve? - why is valvestem orientation (vertical / hor.) important in certain situations? [love]

Hi guys, hope you're all doing well. I'm sheduled for a sales job in the butterfly sector. Although I do have some rudementary knowledge of butterfly valve's I would like to get a heads up for any new / emerging trends in the bussiness. Will the future be stable for the standard rubber lines...

New insights.. I will try 'your' point method, since i used to always used the "project geometry" method before. What i've noticed is that the project option would sometimes fail when projecting 'complex' features. (I guess although this sometimes works it does not mean it's the best way to...

Hi to you all, hope your're all doing well. What 'rules' are there to follow when making guide paths for lofts? Personally i'm having a hard time with these guide paths. Sometimes I get them to work as intendet, other times i simply cannot get them to 'connect' to the section sketches to have...

Greg / Rick, Thank you. In Solidworks Cosmos there is an option shrink fit. Does anyone have experience with this? Would this simply inforce connecting elements regardless the distance betweem the meshes?

On my part there are certain notches on it's circumference that have an initial interference. As such the mesh is also interfering at those locations. The contact condition is set as 'no penetration'. Now, will the solver even see this initial overlap? How is this handled if at all? Or can such...

Thanks corus, We also ran the simulation non-linear in Ansys and the results are similar in that the overal deformation and stress regions are the same but the stresses are much more realistic, i.e. close to or somewhat below yield. I'm just kind of suprised that the stress was extremely high...

I'm doing a FEA on a clamped pipe assembly (bolted with some kind of straps) and i'm somewhat puzzled why the stresses on the pipe are literally of the scale (1000-2000 Mpa). The pipe would probably have some / minor plastic deformation due to the clamping but still... The constraints, loads...

Thanks morienr, that's a good tip thanks brother. In the link below they take 10 as a limit it's more the principle that counts i guess http://www.colorado.edu/engineering/cas/courses.d/IFEM.d/IFEM.Ch07.d/IFEM.Ch07.pdf

guys, I'm interested in the stress on a transition between two parts in an assembly(weld transition). But the stress transition is not smooth between the two parts. This seemed strange to me and i'm wondering why this is. The meshes don't seem to align nicely, but i'm not sure if this is...
