Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications
Packaging Technology and Science, EarlyView.Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and
