Strain Components in Cylindrical Coordinate System

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 theLinear Elastic Materialnode. This, of course, assumes that you can represent the transversely isotropic material in that system.
  • Add aLocal System Resultsnode underVariablesin the Solid Mechanics interface.
  • Add aMatrix Transformnode underDefinitions(Variable Utilitiesmust be activated fromShow More Options).
