Plotting Neutral Axis
Plotting Neutral Axis
(OP)
I would like to create a plot of the Neutral Axis of my 3D composite beam using Abaqus 6.6. So I want to plot the x and y locations of nodes with close to zero stress. I don't care about the z location.
I've looked into XY plots, plotting along a path, and reporting field variables. I'm a new Abaqus user with more ANSYS experience.
Thanks for any help!

I need to model the composite beam in Abaqus, because part of the beam is a model of a human bone from a CVT scan (complicated geometry), and the other part is a bone plate. Also I need to know the stress distribution of my bone plate designs.
Can I somehow query the nodes and get Abaqus to just give my the node number, node coordinate, and S33. I know how to query the nodes for a field variable, but that query doesn't include the location coordinates of the nodes and includes all Stress variables (VM, 1st, 2nd, 3rd, S11 etc).
Worst case I can print out the designs with the same scale and measure them, or do a couple path plots per design and I'll have pick out the data point closest to zero for each path plot.
Thanks Corus!

I think you'll find in the Query tools/probe values part of Viewer that it will show the co-ordinates as well as the stress components and node number. You have to select nodal values though and not element values.
There may also be a way using python script to look at the results file and print out those nodes, and co-ordinates that satisfy a certain criteria. I'd have noo idea hwo to do that though and think that by the time I had figured it out I could have just got the values by hand.

first you have to run your analysis with a new field output request : you will have to ask for the coordinates of the nodes by crossing coordinates in volume/thickness/coordinates.
Then after having run your analysis, report
then choose what U want and setup give you the possibility to order your data as you want to..
