The stress-strain relations are governed by damaged elasticity: (3) where is the initial elastic stiffness of the material; is the degraded elastic stiffness; and d is the scalar stiffness degradation variable, which can take values in the range from zero (undamaged material) to one (fully damaged material).
The concrete material properties used for the simulations are given in Figure 2 and Figure 3.
