stress at location
stress at location
(OP)
Hi everyone,
Is there a way to get the stress at a certain location? This location will not always have a node in this spot.
My mesh changes shape so the nodes change, but i still need to know the stress in one spot (to coincide with the location of a strain gauge in experiments ive done).
The stress (in y-dir) of the closest node would also be sufficient.
Ive tried using node(x,y,z) but then sometimes the closest node is a midside node, for these stress in y-dir is not stored..
im using APDL with version mechanical 14.5
Cheers,
Bram

RE: stress at location
Have you tried modifying your geometry? When we have this issue we create split lines in SolidWorks to the surfaces of interest in order to scope lines or points.
RE: stress at location
Have you tried to use stress linearization (ppath command)?
I dont know exactly how the mesh is but you can get like:
"Your linearized component stress values are obtained by interpolating each element’s average corner nodal values along the section path points within each path element"
by using this command. hope this helps.
RE: stress at location
Thanks for your replies.
In the end i used the SXYZ macro by John Crawford from http://ansys.net/?mycat=search&mytype=Natural&...
It works like a charm!
