Hi, I am applying a strip load on a cylindrical material and I would like to obtain the results of the strain components in cylindrical coordinates (r, phi, a) instead of Cartesian coordinates (x,y,z). The model of the material is linear elastic transversely isotropic.

Can someone help me to figure out how to plot the strain in cylindrical coordinates.

Thank you very much in advance.

Three possible methods (in order of convenience):

  • Use a cylindrical coordinate system in the Linear Elastic Material node. This, of course, assumes that you can represent the transversely isotropic material in that system.
  • Add a Local System Results node under Variables in the Solid Mechanics interface.
  • Add a Matrix Transform node under Definitions (Variable Utilities must be activated from Show More Options).
