In this subsection, we test the forces required to sustain simple shear of a homogenous block. Let us set the block’s height and width to . The depth is chosen so that the block has just one element across the depth, supposing that each element is a brick with equally long edges. The number of elements is than and the block depth is meters.
The surface load, which must be applied to sustain the block’s simple shear, is given by [Taber, 2004]
After exerting coresponding surface loading on the block (for detailed formulae see [Stembera, 2013]), a value of is numerically measured and compared with its assumed value.
