Greetings again! I have another NX Nastran shell element quandary.
I have a question about contacts on the edges of shell elements. I have 2 sheets, perpendicular to each other forming a 'T'. I would like to be able to have non-glued contact between the horizontal sheets face and the...
In my somewhat limited experience, there is no factor of safety in the Ka factor. The FOS is a seperate factor in the calculation of the shaft diameter. Do you know if FOS is standard in your department/company concerning similar designs? I hate xerox engineering, but baselining on succesful...
Well now I feel like a darn fool. It wasnt the offset, it was the proper labeling of the TOP and BOTTOM surfaces in manual contact settings that did it. I evidently didnt do that the first few times, either. D'OH! Now I really look silly.
I still cant get it to cooperate for the automatic...
ESPcomposites and Bailos - Thank you for the suggestions. They led me to find the SILLY mistake I was making. I neglected the offset between the shell surfaces (manual contact, Edit Regions menu) (I left the offset zero in the shell definition our of ignorance for the process). The gap betwee...
I fear that modifying an existing model to approximate the layers may be your best (if not only) option.
There are many models of human bones, muscles, systems out there. The THUMS, Wayne State University has several models at varying levels of complexity, Denton/Humanetics has one of the...
Greetings,
Short version:
I am somehow messing up sheet/shell surface-to-surface contact (not glued)
Long version:
I am currently using NX Nastran 7.0 and dealing with shell contacts. I made a simple model of 2 shell sheets, .5" shell thickness value, stacked on top of eachother (space...
