Non-Cuttable Material - Indestructible Bike Locks

preview

A new material called Proteus is billed as just 15 percent the density of steel, but . That means cyclists around the world may be blessed with for the first time ever.Keep Your Ride SafePeople who want to steal the outdoor furniture from restaurant patios will have to cut the furniture now instead of the cable lock. Most importantly, TV writers will have to work even harder to make it seem easy to get into a locked electrical storage or nuclear facility.Researchers in Germany and the U.K. have teamed up to make a material they say uses harmony and vibration to thwart any attempts to cut it. “Our architecture derives its extreme hardness from the local resonance between the embedded ceramics in a flexible cellular matrix and the attacking tool, which produces high-frequency vibrations at the interface,” they .This content is imported from YouTube.

The process is tricky:“Firstly, the aluminum powder is mixed with titanium dihydride (foaming agent) utilizing a rotating impeller to ensure a uniform mixture. After the mixing stage, the powder mixture is consolidated in a compressor and then extruded resulting in dense rods of material, which are cut into smaller pieces. Next, ceramic spheres and compressed aluminum powder rods are stacked in an orthogonal, grillage pattern and enclosed in a steel box using spot welds. The structure is then heated in a furnace to ca. 760 °C for between 15 and 20 minutes.”Altor SAF Lock$299.00For context, let’s go through a few other examples of reactive materials. Think of a finger trap, where the way the materials are woven holds you tighter as you pull away. That design uses structure against you, narrowing the amount of space and holding your finger tighter the harder you pull. Or oobleck, the classic non-Newtonian fluid made of corn starch and water, where no matter how hard you smack the surface with a flat hand, you’ll never splash into the fluid.🤯Let's get weird.

Even “self-healing” cutting mats, which artists have used for decades, have a microstructure that routes and absorbs the kinds of pressure and blades artists are applying. In the new Proteus material, researchers compare the structure to shooting a bullet into a sandbag. Sand is nothing special by itself, but a bag of sand can slow a bullet simply because of its nature.Related StoryWhen an or water jet cutter hits the ceramic microspheres in the Proteus material, the “attack” is thwarted by strong vibrations or simply dispersal of the stream of water. “The angle grinder achieved only a partial incision and subsequently experienced high wear,” the scientists explain, meaning the angle grinder wore out and dulled before it did meaningful damage.Related StoryDullness, then, increases the vibration reactivity. “Interestingly, the vibrational mechanism was equally effective against the power drill, where the geometry of the drill bits differed significantly from the flat, cutting discs of angle grinders,” they continue. Proteus is the in Greek mythology, able to shift and change like the sea. The researchers explain:"[T]he resistance mechanism was inspired by the vision of Francis Bacon, who wrote ‘this Proteus of Matter, being held by the Sleeves, will turn and change into many Metamorphoses.’ He believed that matter could not be destroyed or annihilated but only reshaped, reformed or transformed into a new geometry, state, or composition."Harmonic vibrations are a hidden cause of potentially catastrophic damage, from more clear sources like earthquakes to the harmonic resonance of bridges. Workers who handle vibrating machinery in factories and machine shops can experience health problems caused by exposure.Advertisement - Continue Reading BelowAdvertisement - Continue Reading Below
