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 the cross-section referring to damage, or, in other words, to a stiffness modification. The nonlinear calculation and the associated layer arrangement of the FE element (see Figure 02) is the basis for the results of this value.

The results of the crack depth are displayed by side and in both principal directions of the cracks. The direction is also able to relate to the trajectories ϕ,hw.
