Metals strengthen with increasing temperature at extreme strain rates

I Dowding, CA Schuh - Nature, 2024 - nature.com
The strength of materials depends on the rate at which they are tested, as defects, for
example dislocations, that move in response to applied strains have intrinsic kinetic …

[HTML][HTML] Convergent laser beam shapes: Unveiling the dynamics of Laser-induced elastic waves in composite materials

A Zarei, G Li, F Pourboghrat, S Pilla - Results in Physics, 2024 - Elsevier
Overcoming the low signal-to-noise ratio (SNR) in laser ultrasonic testing of composite

Single-shot picosecond interferometry for the characterization of laser-driven shock waves

G Saini, SE Kooi, KA Nelson, T Pezeril - Optics Express, 2024 - opg.optica.org
In conventional laser-driven shock experiments, an out-of-plane shock wave is launched
and is typically detected interferometrically after it propagates through the sample. In such …

Excitation threshold of solitons in anharmonic chains

Y Ming - Chinese Physics B, 2025 - iopscience.iop.org
This study numerically estimates the momentum threshold required to excite solitons in
anharmonic chains. For both Fermi–Pasta–Ulam–Tsingou (FPUT)-αβ and FPUT-β chains …
