Non-linear material modeling in ANSYS
Hullo all,
I am using ANSYS to model the non-linear material behavior of wood. The behavior can be described as plastic in compression. I need to assign this material behavior to the Beam 183/184 element. I have the following uniaxial data: Strain Stress (kip/ft^2) 0.00167 184.32 0.000334 36.86400001 0.000668 73.72800001 0.001002 110.592 0.001336 147.456 0 0 -0.00333 -243.36 -0.00458 -308.592 -0.00583 -362.886 -0.00667 -403.207 -0.00792 -423.368 -0.00917 -432.009 -0.02 -377.3 -0.04 -295.24 -0.06 -223.26 I have tried using Cast iron plasticity; but it returns an error ("zero yield stress"). Please note I have to use Beam 183/184 only. How do you suggest I model it? |
