Corus, I dont think its necessary to define the cylindrical coordinate system in the input deck before solve to be able to plot a contour of the displacement in a radial coordiante system, just the viualizer is enough, don't you?

...since I have posted this message no one has responded, quite dissappointing. Took me a while, but I found out a number of things on my own, the summary of which is below. 1) You do not define contact between the bolt shank and the panel holes. 2) A typical joint has the bolt pulling the...

Hello, I have modeled a simple bolted joint with 3 parts: two rectangular plates with 2mm holes in the center stacked on top of each other and a bolt with shank of 2mm and a round 4mm head. The top plate has a slightly bigger hole than the bolt shank's diameter hence there is no thread...

Hello, yes.. that was the question I intended to ask EElmore. I am simulating the assembly loading conditions for doing a stress analysis because we have had these 'bellows' failing left and right and some might have lasted for a maximum of 15mins after loading. The cyclic peak to peak pressure...

Hello, in relation to the change in the Young's modulus, would the posson's ratio also change with temperature??? Thanks.

Actually, I meant how do the Young's modulus and poisson's ratio change. Sorry about that. Thanks.

Hello, I have a part that has three metal sheets made of 1075 steel laser welded together on the outer edges to form an enclosed volume of air that is compressible to take care of some pressure waves in a tube and regulate the dynamics. The question I have is how does the yield strength and...

Bill, that was a great post. I am a full time structural analyst and there are two rules that I follow: If the hardness of the part is in the HRC50 range, then I use the maximum principal stress to compare to the ultimate tensile stress of the material for brittle failure, and if the part does...

Hi Jules, its always a good idea to form groups of surfaces that you think might come into contact before you create the FEM from assembly. Can you see all the elements of the assembly FEM? are you able to see the load set or restraint set pertaining to that particular part FEM when you make...

Hi ESOH, Goto the web site www.download.com Download a software called Snagit, this is basically a screen capture software, it can capture images as well as videos. Install it on your computer (most probably will be a trial version but will be free for a while) It does not care what you are...

Hi zulu, I have been using IDEAS linear static stress solver for the past 1.5 years now. Unfortunately thats the only capability I have right now. So far, I did find IDEAS meshing pretty competitive, like Irwin said. But they do not have a capability to combine constraint sets, hence a...

Hello guys, I have a question about analyzing the diaphragm stresses induced in a peice of sheet metal. Here is the model problem: If you can imagine the lid of a tupper ware box, and imagine that the outer circumference is like a surface, flat, with a small radial thickness to it, take another...

Hello femac, Try this link, I think it has very useful info that generally applies to any FEA program: www.mscsoftware.com/support/library/conf/auc99/p04299.pdf Take care.

Christina, if you have access to Solid Works, one of the very popular CAD programs out there, it can be quite simple to create, Solid Works is quite powerful, although I am not exactly sure how you'd go about creating it. But then, after you are done, you can simply save the part file in one of...

Agree with Brad. Another very important application of a displacement coordinate system other than the global is when you want to apply coupled degrees of freedom between two mating parts that are tightly attached, for example pressed together by an external load, in a particular direction like...

I understand the application of a simple elastic plastic stress strain curve. But what I'd like to know is a source for the stress strain curves for steels, especially accounting for heat treatments. The yield point can vary depending on the treatment etc. even for the same steel. Any tips...

Hi, where can I find stress strain curves for most of the alloy steels in one place, like SAE and AISI steels, tool steels (high strength) etc.? Are there any free internet sources available for them or would I have to buy a book? If the source would also include stress strain curves after some...
