Please see the "Crack Model" option at the Tensile tab of the SBETA Material dialog.

How do you choose between fixed and rotating crack models in ATENA 2D SBETA materials.  According to the Theory Manual SBETA has the option to do either, so where can you change the coefficient? 

Thanks for the help.

In the NLCem2 material family, the "fixed crack" value determines at which max. residual tensile stress level the crack direction gets fixed. In other words, 0.0 means fully rotated crack model, 1.0 fixed since cracking start (see section 2.1.6 Two Models of Smeared Cracks in the SBETA material description in the ATENA Theory Manual), values between 0.0 and 1.0 determine the level, e.g., 0.7 fixes the crack direction as soon it opens so far that the softening law drops to 0.7 times the [initial] tensile strength.

Hello,

It must be possible to choose between a fixed or rotating cracking model. The thing I found about that is the 'fixed crack model coefficient'. Standard the value is 1, but what does that mean?

Does rotating cracking require more calculation time?
