I used the CDP model to create a small solid cubical part. After establishing the necessary boundary conditions, the load is applied. When I check at the stress in my odb file, some of the elements have more stress than the yield stress I entered? Is there an explanation for this?

Hello,

Two things could have happened; either you didn’t enter the CDP parameters correctly, such as units might be wrong or anything else, or when you defined the compressive and tensile behavior, you didn’t control the slope of the diagrams.

Refer to the link below. It might give you an impression about controlling the slope of the diagram. But remember, this isn’t CDP. The CDP is something else.

Check the link below. In these lessons, you will understand the CDP completely.
