Plotting In-Plane Stress for Shells

[james95777]

I am using Mechanica with Wildfire 2.0 to lookat stress in a thin-walled pressure vessel, and I would like to see thein-plane stress at all points on the same plot. By in-plane, I mean tangent to the shell. It's a non-circular shape, so there is tension at some points and compression at some points due to the bending stress.


Is there a way to see this in-plane stress, perhaps creating a curvilinear coordinate system?


I'm aware of the membrane stress and bending stressoptions for shell pairs, but this is an 3-ply shellplaced at a surface, not a midsurface shell, so it doesn't give me that option.


Thanks in advance,


James

For those of you who mayhave had the same problem, I found a way to do this.


In the results window, there is an option to plot Stress YY (or XY, or XX, etc), relative to "Material Orientation". This plots stresses tangent to the shell (or in whichever orientation you need).
