DOI: 10.1016/j.actamat.2016.12.040
Abstract: Abstract Till now, it was widely believed that the dislocation strengthening coefficients used in the Taylor-like relation were universal for a given crystallographic class of materials. In the present study, it is shown that this… read more here.

DOI: 10.1093/gji/ggab278
Abstract: The presence of seismic anisotropy at the base of the Earth's mantle is well established, but there is no consensus on the deformation mechanisms in lower mantle minerals that could explain it. Strong anisotropy in… read more here.

DOI: 10.1093/gji/ggy442
Abstract: Progressive deformation of upper mantle rocks via dislocation creep causes their constituent crystals to take on a non-random orientation distribution (crystal preferred orientation or CPO). The resulting anisotropy of the rock's elastic properties can be… read more here.
