Concrete Damage Plasticity tips.

[Simon012]

Hello Abaqus users,

Can i use the Concreted Damage Plasticity to simulate the damage of Rock material such as Sandstone. Sandstone is a brittle material. and i read in the manual that Concrete damage plasticity is suitable for brittle and quasi brittle material.

I will not introduce any kind of reinforcement for that "Rock" (Sandstone). Hence i guess it might be similar to plain concrete.

I will tell you what i understand and "please correct me if i am wrong".

1- this criterion is suitable for Rock which will be similar to plain concrete.
2-the tension stiffening is used to define the post peak part of the stress-strain curve, and we define it from the tension test (uniaxial tension test?
3-I need one uniaxial test to define the tension stiffening?
4-"compressive behavior" is used to define the hardening part "only" for the uniaxial compression test.
5- only one uniaxial compression test is needed to define the compressive behavior (hardening part).

Please if you have any advice about how to make the model successful, please advice me.

Thank you so much.
