Chelyabinsk Airburst, Damage Assessment, Meteorite Recovery, and Characterization [PDF]

Science, 2013
Deep Impact? On 15 February 2013, the Russian district of Chelyabinsk, with a population of more than 1 million, suffered the impact and atmospheric explosion of a 20-meter-wide asteroid—the largest impact on Earth by an asteroid since 1908. Popova et al. (p.

De-Bonding Numerical Characterization and Detection in Aeronautic Multi-Element Spars

Sensors, 2022
Structural health monitoring has multifold aims. Concerning composite structures, the main objectives are perhaps reducing costs by shifting from scheduled to on-demand maintenance and reducing weight by removing redundant precautions as the insertion of

Characterization of ultra‐heavily damaged NaCl [PDF]

physica status solidi c, 2007
AbstractIn this paper we present the progress made to (i) characterize the defect state of ultra‐heavily damaged rock salt samples with up to more than 20 at% Na colloids, which had been irradiated with 0.5 MeV electrons at 100 ºC up to 104 MGy (1000 GRad), and (ii) understand their physical properties.

An alternative 3D model for damage induced anisotropy and unilateral effect in microcracked materials [PDF]

, 2003
A three-dimensional model of damage by microcrack growth is proposed to account for the mechanical behavior of quasi brittle materials (especially for concrete and rocks). The emphasis is put on the induced anisotropy and on the elastic moduli dependence
