I find myself in a position where I have to run a nonlinear solid element fem. I need to refine a portion of the model and choose to "glue" the two contact bodies. Does anyone know how to specify this in patran 2007. I'm running solution 600.
Note: this model has another set of bodies with...
FEM analysis is quite expensive compared to hand analysis (for a simple problem). Just wondering how people in this forum decide when to use fem over hand analysis.
I have used fem on very large structure such as a 777 fuselage. However, this is a loads model not a stress model (i call it a...
Does anyone know the VBA formula for the current directory? I'm working on an access database that may be moved to other directories and would like to eliminate all the hard coded directories and make it automatic.
Thanks
Greetings,
I have been involved a couple times with hydrogen embrittlement bake oven failures. The last failure was due to power failure. 180+ ksi steel, low HE plating, about 7 hrs at 375F, oven failure, temp dropped to 195F over about 7.5 hrs, then oven restart and bake for 25 hrs at 375...
I've run across this a couple times now and am wondering if there is a non-destructive method to measure the thickness of the nickel plate (this is a repair to a bore)? The base material in this particular case is 30NiCrMo16-6. This is a landing gear part with a nickel repair (without...
I ran across some analysis that substantiates a repair for fatigue based off a damage ratio. The repair damage ratio is calculated based on design ratio multiplied by the ratio of design inertia divided by repair inertia raised to the 5th power.
design damage ratio = .45
repair damage ratio...
Does anyone know what MCAC is? I ran across this acronym within a context that it will be the long term replacement of cadmium plating. Any information you have would be greatly appreciated.
Does anyone know the US equivalent to a British steel, MAT122. Ftu=217 ksi, elongation 7-10%. Do you know a good reference for determining European material compositions?
Thanks for you help.
