Theoretical analysis of ionization of spherical aluminum alloy projectile impacting aluminum alloy target in hypervelocity impact
2021, International Journal of Impact EngineeringCitation Excerpt :All hazards are more likely to be related to the formation of plasma during the hypervelocity impact in three obvious ways, such as providing a short circuit path for the discharge between electronic devices on the spacecraft surface, generating currents to interfere the spacecraft when the plasma expands outward, and producing the electromagnetic pulse when it oscillates. To explore the relationship between the plasma induced by hypervelocity impact and electromagnetic wave, many ground-based experiments had been carried out to detect the microwave [4–6], the electromagnetic field [7–9], and the characteristics of flash [10–14] associated with them, in which projectiles and targets contained not only non-metallic materials such as nylon and polyurethane rubber, but also common metal materials such as aluminum and iron, the collision velocity ranged from 1 km/s to 70 km/s, and the mass of the projectile varied from 10−16∼10−11 g [15] to a few grams [16]. Additionally, many in-situ experiments were done [17–20].
Is the primordial crust of Mars magnetized?
2012, IcarusCitation Excerpt :On the other hand, an impact on an initially non-magnetic crust creates a crater but with almost no strong magnetic signature even if the impact occurs in the presence of a strong core dynamo. Rock magnetic measurements show that shock pressure may result in the acquisition of shock remanent magnetization (SRM, e.g., Srnka et al., 1979; Gattacceca et al., 2010). However, the SRM is significantly less efficient than the thermo-remanent magnetization and it is more susceptible to viscous decay and may not be stable over geologic time (Gattacceca et al., 2007).
Impact demagnetization of the Martian crust: Current knowledge and future directions
2011, Earth and Planetary Science LettersCitation Excerpt :In the absence of a magnetic field, the low pressures (≤ a few GPa) found at this distance are known to demagnetize rocks and minerals (e.g., Borradaile, 1993; Borradaile and Jackson, 1993; Kinoshita, 1968; Nagata, 1971; Ohnaka and Kinoshita, 1968). In the presence of an ambient field, compression at low pressures results in the acquisition of shock remanent magnetization (SRM, e.g., Fuller, 1977; Gattacceca et al., 2007a,b, 2010; Srnka, et al., 1979). It has also been shown experimentally that impacts can generate or amplify ambient magnetic fields (Crawford and Schultz, 1993, 1999) capable of producing a strong SRM in shocked materials.

2008, Earth and Planetary Science LettersCitation Excerpt :and the Lonar basalts would have acquired a secondary viscous remanent magnetic (VRM) overprint parallel to the present-day local geomagnetic field (hereafter PLF). At the time of impact, a new shock remanent magnetization (SRM) could have been acquired during the brief period of shock compression in the presence of an impact-generated or the ambient geomagnetic field (e.g., Nagata, 1971; Srnka et al., 1979; Gattacceca et al., 2007a). The timing and location of acquisition of SRM control the resultant intensity and direction.
