Inelastic response of silicon to shock compression
The elastic and inelastic response of [001] oriented silicon to laser compression has been a topic of considerable discussion for well over a decade, yet there has been little progress in understanding the basic behaviour of this apparently simple material. We present experimental x-ray diffraction data showing complex elastic strain profiles in laser compressed samples on nanosecond timescales...
متن کاملAnomalous elastic response of silicon to uniaxial shock compression on nanosecond time scales.
We have used x-ray diffraction with subnanosecond temporal resolution to measure the lattice parameters of orthogonal planes in shock compressed single crystals of silicon (Si) and copper (Cu). Despite uniaxial compression along the (400) direction of Si reducing the lattice spacing by nearly 11%, no observable changes occur in planes with normals orthogonal to the shock propagation direction. ...
متن کاملNanoscale Molecular Dynamics Simulaton of Shock Compression of Silicon
We report results of molecular dynamics simulation of shock wave propagation in silicon in [100], [110], and [111] directions obtained using a classical environment-dependent interatomic potential (EDIP). Several regimes of materials response are classified as a function of shock wave intensity using the calculated shock Hugoniot. Shock wave structure in [100] and [111] directions exhibit usual...
متن کاملShock compression response of forsterite above 250 GPa
Forsterite (Mg2SiO4) is one of the major planetary materials, and its behavior under extreme conditions is important to understand the interior structure of large planets, such as super-Earths, and large-scale planetary impact events. Previous shock compression measurements of forsterite indicate that it may melt below 200 GPa, but these measurements did not go beyond 200 GPa. We report the sho...
متن کاملShock Compression of Ilmenite
Singleand reflected-shock compression measurements on single-crystal i menite (FeTiO3) to pressures of 635 and 930 kbar, respectively, demonstrate anomalously large compressions above 4320 kbar and imply the onset of one or more major phase changes at this pressure level which continue to occur to at least 4600 kbar. The phase change onset pressure is considerably above the calculated upper bou...
