Figure 5 plots the υ values of 301 silicate minerals (9 cyclosilicates, 43 inosilicates, 219 nesosilicates, 5 phyllosilicates, and 25 tectosilicates) as a function of density at ambient conditions. The transition from the nonlinear regime to the linear regime is produced by the closure of microcracks within samples with increasing hydrostatic pressure (Christensen, 1985; Ji et al., 1993; Kern & Wenk, 1990). The solid elements were analyzed for seven categories (i.e., alkali metal, alkaline earth, transition metal, basic metal, semimetal, lanthanide, and actinide).

Poisson's ratio (υ) is defined as the negative of the ratio of transverse strain to axial strain when an isotropic material is subjected to uniaxial stress (Christensen, 1996; Gercek, 2007; Poisson, 1829; Timoshenko & Goodier, 1970; Wang & Ji, 2009). (2012), Sun, Ji, Wang, Wang, et al. Furthermore, the auxetic behavior of the samples disappears at high pressures (e.g., 500–600 MPa) which are high enough to close almost all microcracks and micropores. The Poisson's ratios of halides, carbonates, sulfides, sulfates, and phosphates were discussed with special attention to the potential auxetic behavior of single crystal berlinite (AlPO4) in the vicinity of its α‐β structure transition (570–580°C and 0.1 MPa) or porous monophase aggregates at ambient conditions. The exceptional behavior of α‐cristobalite has been explained in terms of cooperative rotation of corner‐linked SiO4 tetrahedra (Grima et al., 2006; Keskar & Chelikowsky, 1992; Kimizuka et al., 2007). T. Horibe and R. Kobayaschi, Physikalische und Mechanische Eigenschaften von Karbongestein, Intern. The cell parameters of tetragonal α‐cristobalite are characterized by a = b = 4.9709 Å and c = 6.928 Å at room temperature and pressure. )CrO The sample studied by Kern (1979) was collected from Koli, Finland, while the sample investigated by Barruol (1993) came from the Saint Barthelemy Massif, Northern Pyrenees, France. As shown in Figure 18d, Poisson's ratio increases gradually with increasing P. For example, Poisson's ratio for sample J3 increases from −0.435 at 0.1 MPa to 0.084 at 600 MPa. Rock Mechanics and Rock Pressure; Published: May 1968; Determination of poisson's ratio for rocks by static and dynamic methods. 34, Izd. Metrics details. These values are close to that of quartz polycrystalline aggregate (υ = 0.08 (McSkimin et al., 1965)), suggesting that quartz is the most abundant mineral in these rocks.

Small Bodies, Solar Systems In other words, the auxetic material under the impact densifies in both the longitudinal and transverse directions, inhibiting the formation of tensile fractures and thus resulting in increased indentation resistance. However, some samples containing <10% clay may contain relatively low porosity (2–5%) although these rocks generally show high porosities (6–10%), presumably depending on the degree of compaction between the silicate clasts.
