I have re-done the mesh at each length and the quality looks good. Its an extremely simple geometry so the auto mesher should have no trouble with it.
I tried to figure out what type of elements I am using and it stated that they are solids. I varied the number of points up to 16 and get the...
Thanks Greg,
Vibrations was never one of my stronger subjects. Could you direct me to the equation that I can verify the frequencies with by hand cals?
I have been conducting a modal analaysis of a long tube hanging vertically. The tube is constrained at one end and free at the other.
For lengths less than 2m, the natural frequencies obtained from COSMOS seem reasonable. However, at lengths greater than 2m, I am getting a negative natural...
As requested, I am up loading a sketch of the loading conditions I am dealing with. Hopefully this helps clarify things. Thank you for all the feedback so far.http://files.engineering.com/getfile.aspx?folder=342e2c21-c36a-4372-b820-67560932a94a&file=Loading_Conditions.ppt
I am trying to figure out the actual stress for a pipe that is fillet welded to a plate. The pipe is cantileved off of the plate and loaded at the end. So, the largest stress is located at the weld.
Can anybody direct me to some literature that explains how to handle this? I assume there are...
I do realize that the majority of "other" has to be made up of iron. My concern was that the iron may be contaminated with trace amounts of lead, cadmium or mercury. It really does not take much of any of these three elements to put them over the allowable limits to RoHS.
So, can I assume...
I have a general question about a 316 stainless steel part we will be fabricating that we require to be RoHS compliant for our customer's application. The RoHS directive restricts the use of certain hazardous substances to the following levels for stainless steel:
Lead – Pb 0.35%
Mercury – Hg...
