On the contrary, when shale is under tensile loading, the bonding strength of the bedding planes decreases, forming a large number of microcracks, which then propagate and intersect each other.
The figure shows that pore water pressure plays a crucial role in the development of microcracks in concrete specimens, thereby aggravating penetration damage of specimens.
In PF[C.sup.2D] software, only when the stress intensity transmitted between the particles is larger than the parallel bonding forces between the particles, the microcrack can be generated.
Herein, we fabricated a series of small modules using solar cells with different microcrack lengths.
Since the damaged mudstone can not be healed to intact rock, unhealed microcrack area [A.sub.uh] is greater than 0, which means the damaged part of mudstone can not heal completely under any circumstance.
The boundary element method (BEM) is an effective method in solving microvoid and microcrack problems, since only the boundary of the analyzed domain needs to be discretized [20].
However, the original microcrack closure stages are unobvious, and strain-softening behavior and residual stage can be more easily identified compared to those of the coal specimen.

Sometimes microcracks will hit a void spot or other imperfection in the metal and stop growing.
The stress concentration and the microcrack propagation should be responsible for the spalling of TiN-matrix coatings.
