In RF-CONCRETE Surfaces, the crack depth is displayed in connection with the nonlinear calculation. What is behind this variable?


The crack depth is used to specify the height of cross-section referring to a damage, or in other words to a change of stiffness. The nonlinear calculation and the associated layer arrangement of the FE element (see Figure 02) is the basis for the output of this value.

The crack depth is displayed on each side and in both principal directions of the cracks. The direction can also be understood with the trajectories φ,hw.
