Previous research has described the effect of the loading rate on the microcracking activities of RC and RCR samples [15, 27] but did not deal with the influence of the height ratio on the microcracking evolution of composite samples, which is a key issue to be investigated in this work.
The microcracking initiated from the surface pitting, and virtual stress increased with the progress of pitting corrosion.
The combination of tension and shear microcracking together with sliding in biotite basal planes was found to control the failure of specimens with sub-horizontal foliation.
Figure 8 shows the existence of surface polishing, microcracking, and detachment of wear particle.
It has been recognized that immediately ahead of a moving crack is a zone of microcracking called the process zone.
[9] investigated post isothermal aging of CuAl ball bonds are mainly attributed to CuAl IMC interface corrosion and induce interface microcracking. However, there are limited studies on the wearout reliability of palladium-coated Cu wire, bare Cu wire, or Au wire bonds in nanoelectronic device packaging.
These composites have to be thicker and heavier to compensate for the microcracking. Nanofillers can prevent microcracking and, hence, toughen composites.
The brim and diagonal of indentation are very clear, and little microcracking is found around the indentation.
Future revisions likely will address microcracking brought on by Pb-free materials and processing that makes boards more brittle.--MB
