The overall fraction of rods and the fractions of rods along the longitudinal and transverse axes were also correlated with the measured microcrack density.
Although most of the predicted yielded tissue was found in longitudinal plates (73 ± 11%), the measured microcrack density was positively correlated with the proportion of the yielded tissue in longitudinal rods (R2 = 0.52, p = 0.02), but not in rods of other directions or plates.
Loading was stopped at fracture or 106 cycles, whichever occurred first, and microcrack density and length were measured in the loaded region and in a control region that was not loaded.
Faoro et al. ([2013]) provide a model for how microcrack density within an isotropically microcracked sample can be modeled as a function of aspect ratio and microcrack connectivity.
We empirically correlate the microcrack density of the andesite to the measured physical properties.
In other words, the microcrack density typically increases with increasing tensile load.
Microstructure refinement and reduction in microcrack density were observed after hot working.
1) What are the relationships of sample size to variability in microcrack density results and the probability of crackless specimens?
There also was a trend for bone from dogs with low osteocyte lacunar density to have a higher microcrack density, but not higher porosity.
Relationships between the relative mechanical properties and the microcrack density were established.
