RADIOSS solver - Strain in Y when sheared in XZ and a strain in X when sheared in YZ

RADIOSS solver - Strain in Y when sheared in XZ and a strain in X when sheared in YZ

(OP)
Hello everyone,

I've attached the BCs and and the load applied, it is a one element model.

Honeycomb material law (28) is used, with co-rotational formulation. The r,s,t are correctly defined, with 't' being the out-of-plane direction and 'r' and 's' being the in-plane. A solid orthotropic property was set for the honeycomb, and full integration was used.

I am facing the following issues:
-RADIOSS output (follows) the input XZ yield curve when the model is sheared in YZ, and outputs (follows) the input YZ yield curve when the model is sheared in XZ
-a strain in Y direction (unexpected) when the model is sheared in XZ direction
-a strain in X direction (unexpected) when the model is sheared in YZ direction

Does anyone know what's the problem here?

Best,
Sushant
