So we don't have a listing for sand or silica aka quartz despite sand being pretty fricking common. Sand is basically these grains that you find in deserts and beaches, the former being more useful as the common feat for burrowing through the ground very much requires it.
The values for sand are as follows:
Fragmentation: 96.3 kPa (0.0963 j/cc) (Google extracted that part from a paywalled part from here: https://link.springer.com/article/1...le, under the normal,clay samples is 56.4 kPa.
V. Frag: 172.36 kPa (0.17236 j/cc) (https://www.researchgate.net/public...gation_of_the_Strength_of_Carbon-sand_Mixture )
Pulverization: 1 to 1.2 MPa (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6835750/ )
Silica aka quartz, on the other hand, is weird... So, it is commonly agreed that quartz has a tensile strength of 48 MPa, equivalent to a shear strength of 28.8 MPa using the 60% rule.: https://www.qsiquartz.com/mechanical-properties-of-fused-quartz/
On the higher end, one source that, imo, doesn't seem very trustworthy puts it's shear strength at 70 MPa: http://www.mt-berlin.com/frames_cryst/descriptions/quartz .htm
Yet AZOM puts it's high-end tensile strength at 155 MPa, which is equivalent to 93 MPa using the 60% rule: https://www.azom.com/properties.aspx?ArticleID=1114
As for compressive strength, every source I've seen for it lists it at a whopping 1100 MPa! Like, wow! Anyway, here are the destruction values for quartz itself:
Fragmentation: 28.8 j/cc
V. Frag: 70-93 j/cc
Pulverization: 1100 j/cc
Since these materials are both common af, should we have these added to the destruction values list?
