but I dont find formula including of relationship between cube strength of concrete and fail.surface excentricity.
can you say in which sheet of Atena Theory this formula is exist or type it.

However, in general, if you do not have any measurements for a specific material parameter, the best usually is to use the value generated from for the cube strength or for the closest corresponding concrete class.

I want to  define new mateial with 3D Nonlinear Cementitious 2 >>miscelaneous
how calculate the fail.surface excentricity .
thanks.
