converting strain tensor from Cartesian to cylindrical coordinates
converting strain tensor from Cartesian to cylindrical coordinates
(OP)
Hi,
This may not be directly related to Abaqus CAE or Abaqus. But I was hoping to generate the strain tensor in a cylindrical coordinate system, and need some help. I was able to use Python to read the 6 NE components from Abaqus odb file after Explicit run. I was also able to construct the strain tensor 3-by-3 matrix. I just need to convert the strain components from the default Cartesian coordinates into a cylindrical coordinates. I know I can do that in Abaqus CAE by creating a cylindrical coordinate system, but how can I do this by writing my own program? i.e., what is the formula? Thanks very much!!

If you got an existing derivation somewhere, that'll be much appreciated!

Any idea exactly what is happening? Or how to rectify? Thanks.
