Transport composite fuselage technology: Impact dynamics and acoustic transmission [PDF]

open access: yes
A program was performed to develop and demonstrate the impact dynamics and acoustic transmission technology for a composite fuselage which meets the design requirements of a 1990 large transport aircraft without substantial weight and cost penalties. The

Phases of lattice hard core bosons in a periodic superlattice

open access: yes, 2010
We study by Quantum Monte Carlo simulations the phase diagram of lattice hard core bosons with nearest-neighbour repulsive interactions, in the presence of a super-lattice of adsorption sites.

Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Effect of trapezoidal pattern on deflection of sandwich panel with corrugated core

open access: yesNihon Kikai Gakkai ronbunshu
The deflection behavior of square sandwich panels with corrugated core of trapezoidal cross section at different pitch lengths and heights of trapezoidal pattern was investigated using the FEM analysis, where the panel size was fixed at total height of ...

Analysis of Corrugated Core Sandwich Panels

open access: yes
Abstract The demand for light weight sandwich panels are becoming increasingly important as multi-functional components in many areas. The tremendous need of these light weight modular structures have application in bridge deck slabs, partition walls, roof slabs etc. Corrugated core sandwich panels are composite structures in which a corrugated

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

open access: yesJournal of Field Robotics, Volume 43, Issue 2, Page 1068-1090, March 2026.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Structural efficiency studies of corrugated compression panels with curved caps and beaded webs [PDF]

open access: yes
Curved cross-sectional elements are employed in structural concepts for minimum-mass compression panels. Corrugated panel concepts with curved caps and beaded webs are optimized by using a nonlinear mathematical programming procedure and a rigorous ...

Spontaneous Intercalation of Graphene on Sapphire

open access: yesSmall Methods, Volume 10, Issue 5, 9 March 2026.
When left at room temperature, even in depressurized atmosphere, foreign molecular species can intercalate in between graphene and the (31$\sqrt {\mathbf {31}}$×$\times$31$\sqrt {\mathbf {31}}$)R9∘$^{\circ }$ reconstruction, effectively decoupling the graphene from its substrate: αAl2O3$\alpha {\rm Al}_2{\rm O}_3$(0001).

Spectral gap induced by structural corrugation in armchair graphene nanoribbons

open access: yes, 2010
We study the effects of the structural corrugation or rippling on the electronic properties of undoped armchair graphene nanoribbons (AGNR). First, reanalyzing the single corrugated graphene layer we find that the two inequivalent Dirac points (DP), move

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

open access: yessteel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed
