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.
Increase in surface roughness along the scratch groove is due to localized plastic deformation, crazing, microcracking
, fish-scale formation, plowing developed during the scratch process and can be correlated with the scratch depth for some polymers (2).
Damage mechanics simulate in equivalent continuous media, the deterioration of materials exclusively owing the microcracking
Nanofillers can prevent microcracking
and, hence, toughen composites.
While this flexural capacity does meet industry requirements, it is accompanied by distributed microcracking
, which might cause concern for material durability under harsh environmental conditions and mechanical loads.
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.
the elastic change of cross sectional area due to Poisson's ratio effects and the dilation due to microcracking
It was anticipated that internal damage and microcracking
in overstressed wood would create discontinuities within each member, in which case acoustic velocity would potentially be able to detect damaged wood.
It is easy to machine and less abrasive to cutting tools, and it resists the microcracking
associated with engineering thermoplastics, says CMT.
NWA' s exhibit good registration stability and inhibit resin microcracking
due to random microfiber reinforcement, making it an ideal substrate for laser mierovia and HDI applications.
