How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...

Ono Suparno

Dear Mr Narasimha,

Could you please explain in more detail what do you mean with "mesh between matrix and fibbre".

Regards.

Bala Narasimha Guniputi

Beam is of rectangular cross section 250 * 20* 2 mm. in this i want to embedd the 0.1 mm fibre along the direction of length.

when i am meshing, saying shape warning limits leads to poor results.

when the reinforcing fibre is of very small in dia , meshing wil be the problem, because of very small element sizes.

please give any suggestions, to overcome these problem

Padmanabhan Krishnan

Transition elements or interface elements between the matrix and the fibre is recommended. Any way, there is a modifed zone isn't it ?
