Summary: The study investigates the 2.5D dynamic response of a half-space to an internal point load moving at suband super-critical speeds using both analytical and numerical approaches. By converting the partial differential equations of waves to ordinary differential equations via Fourier transformation, a multiplying factor is derived to account for load dissipation at different velocities. The findings include similarities in solutions for fast-moving point loads and line loads using 2D and 2.5D approaches, and increased displacement of the half-space with the self-frequency of the moving load.

Summary: We demonstrate a strong enhancement of third harmonic generation in an amorphous silicon metasurface consisting of elliptical nano resonators, which is attributed to a new type of multi-mode Fano mechanism. Theoretical predictions are confirmed experimentally through linear and nonlinear transmission spectroscopy. Furthermore, quantitative nonlinear measurements reveal an absolute conversion efficiency of eta(max) approximate to 2.8 x 10(-7) at a peak power intensity of 1.2 GW cm(-2), with amplification factors of up to similar to 900 compared to unpatterned silicon films of the same thickness. Our findings open up possibilities for utilizing strong Fano-type multi-mode coupling in metasurfaces for high third harmonic generation in various applications.

Summary: Metallic nanowires are widely used as small-scale structural materials due to their small volume and high strength. The mechanical properties of nanowires in pure metals are well understood, but the deformation in metallic alloys is still unclear. In this study, we perform atomistic simulations and find that dislocation slips and twinning control the plastic deformation of nanowires in refractory multi-principal element alloys (RMPEAs). Furthermore, we discover that RMPEAs have reduced tension-compression asymmetry compared to pure metals.

Summary: This study proposes a novel multifunctional microlattice metamaterial based on a hollow truss-plate hybrid design, which is realized by digital light processing 3D printing. Experimental results show that this material exhibits excellent sound absorption and mechanical properties, achieving quasi-perfect sound absorption and broadband half-absorption. The sound-absorbing capacity relies on the designed cascaded Helmholtz-like resonators, and the physical mechanisms behind the absorptive behaviors are revealed through numerical analyses. Additionally, this material displays superior modulus and strength compared to conventional cellular materials and modified microlattices, attributed to the near-membrane stress state of the plate architecture and the mechanically robust behavior of the hollow struts. This work presents an effective approach for designing and engineering multifunctional metamaterials through 3D printing.

The study shows that the second-order hierarchical honeycomb has superior crashworthiness compared to regular and first-order hierarchical honeycombs, and determines that the circle is a suitable matching geometry in improving the crashworthiness of a square-based honeycomb. The Square-Circle-Circle structure is ranked as the optimum for crashworthiness application using Complex Proportional Assessment.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.
