The "Material" frame serves to choose parameters of the material adopted for blocks or cover. Defining materials depends on the selected type of "Geometry". The first type of geometry (structure with blocks) requires inputting the unit weight of blocks γ, cohesion c, friction f, and shear bearing capacity of joint Rs [kN/m].
The other types of geometry (structure without blocks) enable to consider a cover, which requires inputting the unit weight γ and shear resistance Rs [kPa].
If the soil between the reinforcements is different than soil assigned to the geological profile, then the program allows us to specify this soil by checking the option "Input different reinforced soil". Subsequently, in combo list user selects the type of soil (the combo list contains soils introduced in the frame "Soils").
