I am trying to create charts of a user defined result vs distance along a concrete RC beam. I am particularly interested in the normal and shear stresses at the interface between two concrete layers. I have defined a path spanning the length of my beam which runs along the centreline of the top face of the beam. I have turned on the mesh and snapped it to the mesh nodes. I want to setup a user defined result for the ratio of normal stress to shear stress but for some reason the normal and shear stress results, when scoped to a path will not come up with the identifier field required to do this.

Can someone please help me with this?

If not is there some way I can manually export the tabulated data for both the normal and shear stresses as functions of position x along the beam to be configured and plotted externally of Ansys?

Hello, 

Try creating a User defined result scoped to this path with the expression dividing normal stress and shear stress. An example is shown below. 

You need to be careful that the denominator is not zero (which might result in infinite value).

 

Hope this helps. 

Best regards,

Thank you very much. I was not aware that preset 'identifiers' for normal and shear stress existed.

Also, you can find a list of all the available expressions by clicking on Worksheet (after solution) as shown below (see the 'Expression' column). You can insert a result directly by RMB on any line in this list --> Create User Defined Result.
