The required energy for crack propagation

Asked by Mahmoud Ashour

Hello,

I'm doing a simulation to model the crack in concrete during an uni-axial tensile test with a geometry contain a notch.
I'm trying to understand the constitutive law beyond CpmMat. As an example the energy criterion for fracture of the concrete. unfortunately, I'm not able to find such an information. does anyone have information regarding this topic?

Many thanks in advance

Best regards,
Mahmoud

Hello,

read Václav Šmilauer's thesis [1], section 3 (Concrete particle model).
If you are already familiar with it, please provide more information.

Cheers
Jan

There is quite a bit of functionality on tracking energy release of bonds in the JCFPm model:

In case it interests you.

Can you help with this problem?
