High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Continuum nanomechanics for nanocrystalline and ultrafine grain materials

IOP Conference Series: Materials Science and Engineering, 2014
An extension of the classical continuum mechanics model is provided for the solution of boundary value problems at the nanoscale. The resulting continuum nano-mechanical model is based on the introduction of new terms to account for the interaction of bulk and surface points of the medium, which becomes significant as the specimen size is reduced down ...

The mechanical properties of ultrafine-grained metals at elevated temperatures

, 2009
Ultrafine-grained materials, having grain sizes in the submicrometer or nanometer range, may be readily produced by processing bulk solids through the application of severe plastic deformation (SPD) and this leads to the possibility of revealing ...
