Figure 10 shows the comparison of cracking patterns
for specimen SW4 .

The notorious relative displacement between nodes is obtained by numerical model, which is similar to the cracking pattern
of the experimental test , as shown in Figure 8(a).
In the reference model, the cracking pattern
and the max crack widths were affected by change of FE mesh size, whereas it was far less sensitive after scaling.

The PMF-strengthened beams were again placed on the same loading frame setups (as specified in Figure 2) to find their ultimate shear load-carrying capacities, deflection, and cracking pattern
. The locations of LVDTs were kept the same as in the case of controlled beams.
Moreover, the crack opening of the PE fiber-reinforced system corresponding to the maximum fiber bridging stress is larger than that of the steel-fiber-reinforced system, which will be discussed later in relation to the cracking pattern
Even the failure mechanism is the same observed for the other specimens, that is, the typical cone-shaped cracking pattern
due to the rigid dislocations of cob elements seen in Figure 8.
Conservation Status of the Church: Cracking Pattern
. The church presents a diversified cracking pattern
characterized by horizontal and vertical damages (Figure 4).
Patterns in the blood droplet from healthy adults dried on glass substrates consist of three distinct zones with different characteristic cracking patterns
(Figure 8(b)), namely, a fine peripheral region adhering to the substrates, a coronal region with regularly ordered radial cracks and large-sized deposit plaques, and a central part with disordered chaotic cracks and small-sized deposit plaques .
