@bwspenc @gambka thoughts on this? Do they need to implement a new smeared cracking stress material that can handle anisotropy? |

Hi everyone,
I am testing a simple study where I apply a volume averaged strain in the transverse direction (x) of my material (a 2D cross section of a unidirectional fiber-reinforced composite). My material is transversely isotropic, and I specified the stiffness tensor for block 1 (my fiber phase) and the isotropic modulus and poisson's ratio for block 2 (matrix phase).
My script is shown below. It should be noted that the subdomain ID is my material microstructure (which is a two-phase binary structure). I then assign appropriate constituents based on whether the phase is 0 or 1. The script is quite long because of this insertion, but I included it so that you can run the input file.
I am receiving this error for ComputeSmearedCrackingStress:
*** ERROR ***
The following error occurred in the object "elastic_stress", of type "ComputeSmearedCrackingStress".
ComputeSmearedCrackingStress requires that the elasticity tensor be guaranteed isotropic
I would appreciate any advice on how to circumvent this issue.
