High‐pressure elastic properties of major materials of Earth's mantle from first principles
BB Karki, L Stixrude… - Reviews of Geophysics, 2001 - Wiley Online Library
The elasticity of materials is important for our understanding of processes ranging from brittle
failure, to flexure, to the propagation of elastic waves. Seismologically revealed structure of …

On amorphization as a deformation mechanism under high stresses
In this paper we review the work related to amorphization under mechanical stress. Beyond
pressure, we highlight the role of deviatoric or shear stresses. We show that the most recent …

Shock-induced amorphization in silicon carbide
While silicon carbide (SiC) has been predicted to undergo pressure-induced amorphization,
the microstructural evidence of such a drastic phase change is absent as its brittleness …

Unifying two criteria of Born: Elastic instability and melting of homogeneous crystals
The criteria formulated by M. Born for the onset of melting (1939) and lattice stability (1940)
are re-examined on the basis of more general considerations of elastic instabilities. With the …
