In all of the crippling calculations I've done over the years, I've always used Fcy as the cutoff stress. I'm trying to get a little more out of something, and noticed that in McCombs' Bruhn Supplement, at the end of Art. C7.30, he mentions people have used 3 different cutoffs: (1) Fcy, (2)...
I have been running dongle licensed FEMAP v9.2 and NEINastran v8.25 in Windows XP for years. I just upgraded to Windows 7, and am having trouble getting them to load/run. Has anyone done this recently and have helpful advice to share? Thanks in advance, and I can give more details on the...
Hello All - I need to power a pressure transducer with 5V and I have a computer nearby. USB provides 5V, but it is not regulated enough for the pressure transducer. Does anybody make a device that you plug into a standard USB hub, but regulates/filters the power out to a better level, say...
Is there a test that can be done to determine grain direction of stainless 301 1/4 hard sheet? A part has been installed, but grain direction is not known. Specifically, is there a test that could be done installed - meaning tests that don't involve bending the sheet, etc.?
Thanks,
Luke
I can plot freebody displays in FEMAP to calculate the total load on a section. The total loads are shown on the screen by selecting the 'Show Load Summation' checkbox. My question is, is there anyway to ouput/list this data? I want to automate this for several sections, but haven't been able...
Here is a problem I've run into. Normally, when you constrain nodes in femap, the constraints are indicated visually with a cyan triangle and a 1, 2, and/or 3. However, on a model I am building, this is not happening. Instead, they display as a small green square, with no directional...
Hello All,
Are there any other "report style" software alternatives to MathCAD? I have to present technical reports of calculations, and I love how mathcad presents it in a readable format and the equations are "live". However, I'm not doing any substantial math work, only...
I'm doing some research on Solidworks. Is anybody using solidworks to design FAA certified aircraft structure? If so, is it new design or sustaining? Have you had success with lofts/splines/large assemblies?
Thanks for the input,

I'm doing a bit of research about SW. How many of you are using solidworks to design FAA certified aircraft structure? If so, is it new design, or sustaining?
Thanks for the input,

Does anyone have guidelines for acceptable temperatures that a given alloy can be raised to and then cooled again to room temp without affecting its mechanical properties? I have a shrink fit bushing (C63000 nickle alum bronze) in a housing (AL 7050-T7451). I am curious how hot I can heat the...
I want to spec a strut pressure filler valve. The spec numbers I have are AN6287-1 and MS28889L-2. The MS s/s the AN, however, as of 12-1-95, MS28889L is inactive for new design, but no replacement is listed. Can anyone suggest a current, valid replacement?
Thanks for the help.
