Modeling Properties in STKO

[Sadegh]

Hello,

As attached, I am trying to model a masonry wall with ASDCONCRETE3D material and ASDSHELLQ4, the problem is that the peak load results does not change, it changes only with fc, but the failure is in tension. I changed ft, E, Poisson, but did not have effect. Does the program calculate these itself?

Thank you,

[Sadegh]

Also, another question. In this type of modeling how the software calculates poisson coefficient in post peak condition, when the damage has happened...

Thank you,

This is not clear to me. What do you mean by "the failure is in tension"?

The poisson's ratio in the PhysicalProperty Editor is for the elastic part of the model.
When the damage/plasticity happens, the elastic poisson's ratio remains the same, but you may experience a dilatant behavior under shear loads. Are you referring to this?
