Deep beneath the hillsides and suburbs of Brazil, there are tunnels so vast and regular that they look like abandoned subway ...

To better understand the penetration mechanism of the elliptical cross-section projectile (ECSP) into semi-infinite concrete target, penetration experiments using three types of ECSPs with different ...

The effect of soil constitutive models, nonlinearity of the barrette material, loading direction as well as the cross-sectional shape and second moment of inertia on the response the barrette ...

Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers have now derived an equation describing this phenomenon, demonstrating that ...

Tsukuba, Japan—Pressure waves propagating through bubble-containing liquids in tubes, known as "bubbly flow," behave distinctly from those in single-phase liquids, necessitating precise understanding ...

Mechanical systems with moving contact points, like rolling, sliding, and impacts, are standard in engineering and daily life. Analyzing these systems becomes more complex when objects interact with ...

How few corners can a shape have and still tile the plane?” mathematician Gábor Domokos asked me over pizza. His deceptively simple question was about the geometry of tilings, also called ...

Large amounts of dust are generated during digging operations in underground mines, and the transportation of dust is affected by the shape of the roadway section. In order to know the dust ...
