Experiments on Wedge Indentation of a Porous Material : Indentation Hardness of a Porous Material, 2nd Report

Material-independent crack arrest statistics: Application to indentation experiments

An extensive experimental study of indentation and crack arrest statistics is presented for four different brittle materials (alumina, silicon carbide, silicon nitride, glass). Evidence is given that the crack length statistics is described by a universal (i.e., material independent) distribution. The latter directly derives from results obtained when modeling crack propagation as a depinning p...

Simulations of HIHEX Experiments at FAIR Using Porous Material

Heavy Ion Heating and Expansion (HIHEX) technique [1, 2] has been proposed to study the equation-ofstate (EOS) of high-Energy-Density (HED) matter using intense uranium beam at the future Facilit for Antiprotons and Ion Research (FAIR) [3]. Previously we considered solid material for such studies whereas in the present work we use porous targets that are heated by the above ion beam. Numerical ...

Porous Silicon—A Versatile Host Material

This work reviews the use of porous silicon (PS) as a nanomaterial which is extensively investigated and utilized for various applications, e.g., in the fields of optics, sensor technology and biomedicine. Furthermore the combination of PS with one or more materials which are also nanostructured due to their deposition within the porous matrix is discussed. Such nanocompounds offer a broad aven...
