I'm working on a model with several drawing sheets already created. Now when I attempt to create a new drawing sheet in the drafting module, it gives an error stating "A buffer was overwritten by the TEXT module" and does not work. If I erase all of my previous sheets, it works, but I don't want...
I have a model file (not an assembly) that contains a number of bodies that are all sorted into groups. NX 1872.
I'm creating the 2D views in Drafting now. I need to show several drawing views that contain varying combinations of groups. Is it possible to show and hide groups in an individual...
Let's say I have an aluminum skin, carrying a compressive load over distance "a" from frame to frame, and supported by longitudinal stiffeners equally spaced at width "b". I am sizing everything, having the required loading in lb/in. After selecting a skin thickness I can get the buckling stress...
We have been transitioning a lot of our NDI procedures to remove fasteners and inspect with bolt hole eddy current. A lot of them are through stacked structure, say 3 layers of aluminum that are not taken apart. We are getting a lot of what I'll call false positives, crack indications that...
Let's assume an integrally stiffened I-beam under axial compression. As I understand it, the free-edge flanges will buckle first. As load continues to increase the corners and web will eventually buckle. The crippling stress Fcc of this test sample is basically then a P/A, an average stress of...
Does anyone know of any good references to use for freeze plugs? I'm looking for something that covers aluminum, titanium, and steel alloys and the primary use is for repairing bad fastener holes in aircraft structure. I'm looking to find:
- the appropriate amount of interference to use with...
Is there any published data to go by for PH13-8MO in the solution treated/annealed condition? MMPDS and the other references we have in our office say that 13-8 should not be used in this condition but do not say why. We have some CSI's on our aircraft that should be heat treated to the H1000...
On typical sheet metal structures, we want a fastener countersink depth to be no more than 2/3 of the part thickness to avoid a knife-edge condition. Let's say I have a single part made of three sheets of .040 thick material that are bonded together to give a total stack up of .120 thick. I want...
I am modeling a wing skin which has the outer surface defined by loft data that I have a surface model for in NX. Some areas of the skin have a tapered thickness, ie, tapering linearly from say .180 thick at one point to .120 thick further outboard. What's the best way to model this? I am trying...
