Modelling of a quasi-brittle material using concrete damage plasticity

[AravindanS]

Hi..

i am having a material that behaves as a quasi-brittle material in a operating temperature range. So I thought of modelling it using concrete damage plasticity(CDP) model using ABAQUS..

1. Is that right Or to what extent it is possible?
2. What are the details I need to know about the material, so that i can model it as a CDP.. I saw some journals.. They said u need to have
a. 1D Stress-strain curve (tension and compression)
b. bi-axial failure in plane state of stress
c. tri-axial state of stress..

The problem is I'm modeling a material, which doesnt have real-time experimental data - (As I said, operating temperature is very high) - . What should I do in that case..

Thanks in advance.
