Perforation of welded aluminum extrusions

EPJ Web of Conferences, 2015
A purely numerical procedure for predicting the perforation resistance of welded extruded AA6082-T6 aluminum profiles is presented in this study. The numerical work was conducted completely independent of the experimental tests that were only used for ...

Finite element simulation of ballistic impact on composite plates

, 2021
In this study, effect of reinforcement type and different numerical composite damage material models were investigated in high velocity impact applications. Aramid and carbon-aramid hybrid fibers were used as a reinforcement material and epoxy was used as matrix in the composite plate.

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 14, 23 September 2026.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

Gas Measurements Reveal Fractional Degassing and Water Interaction During a Flank Eruption of Pacaya Volcano (Guatemala)

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.

Unveiling the armor: experimental study on ballistic impact resistance of silica aerogel, sorbothane, and graphite sandwich composites

Discover Materials
Ballistic armour is intended to save lives by absorbing the impact of bullets and preventing them from entering the wearer’s body. Especially for police enforcement, security, and military professionals.

Numerical Simulations of 3D Scattering Structures Reveal Systematic Underestimation of Marsquake Magnitudes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14964-15009, 15 September 2026.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.
