Stress Linearization using PyDPF-Core

[mariahua]

Hello!

Is there a way to perform stress linearization (where stresses are separated into membrane and bending stresses along a path) using PyDPF-Core?

Currently, I am using the following process to compute the membrane and bending stresses:

1. Extract stress data using dpf.operators.result.stress_X
2. Map the stresses onto a defined path using dpf.operators.mapping.on_coordinates
3. Perform the linearization as described in the Ansys docs using numpy.

Using this process, the results are close but not exactly equal to my colleague's APDL script, so I'm thinking I have an error somewhere. If there were a built-in PyAnsys function for stress linearization, that would be helpful!

Stress linearization is described in the Ansys docs here:

Thank you!
