The shear failure was characterised by bed joints sliding and vertical joints opening, contributing to the development of stepped diagonal opening without visible cracking in the block units as shown in Figure 5(a) and (b) for W1 and W2.

If we repoint a stone wall with stiff, strong, sand and cement mortar, then the normal flexing that happens between the stone slabs on lime mortar bed joints, will crack the new pointing, allowing water to seep behind the pointing and after a few hard frosts, the new pointing will break away in big lumps.
In masonry, upon shearing along bed joints, brick units also undergo upward translation, causing global volume increase.
This state is accompanied by a process when at first tension cracks typically arise and bed joints open up, and the areas around the cross sections in which the joints were formed, ie the areas where the resultant of the tension leaves the cross-section core, are locally degraded.
