Figure 9: Displacement Factor (DF) variation against alfa and beta

In Figure 10, two different wedge inclination layouts have been considered in order to see how the LF changes with different friction coefficient values. As seen in this figure, the LF increases with a reduction in the friction coefficient, for this reason it is necessary to have the lowest value between the wedge components and the blocks.
