Smart Materials Based on Shape Memory Alloys: Examples
WebSep 13, 2024 · There are numerous examples in which they replace metal wires in orthodontics: although the polymeric thread has mechanical properties of resistance to stress and fatigue lower than that of metal, it has a much lower aesthetic impact, increasing patient satisfaction. 2. Shape Memory Polymers in Bandages WebSep 14, 2016 · Smart structures are used in several shape and vibration control applications. Micro positioning, satellite antenna shape control, space structure shape correction, and automatic flow control valves are some of the practical examples of … One example is the prevalence of dental braces using SMA technology to exert constant tooth-moving forces on the teeth; the nitinol archwire was developed in 1972 by orthodontist George Andreasen. This revolutionized clinical orthodontics. See more In metallurgy, a shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It may also be called memory metal, memory alloy, smart … See more The shape memory effect (SME) occurs because a temperature-induced phase transformation reverses deformation, as shown in the previous hysteresis curve. Typically the … See more SMAs display a phenomenon sometimes called superelasticity, but is more accurately described as pseudoelasticity. “Superelasticity” … See more Many metals have several different crystal structures at the same composition, but most metals do not show this shape-memory effect. The special property that allows shape-memory alloys to revert to their original shape after heating is that their crystal … See more The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (NiTi), but SMAs can also be created by alloying See more Shape-memory alloys have different shape-memory effects. The two common effects are one-way SMA and two-way SMA. A schematic … See more The first reported steps towards the discovery of the shape-memory effect were taken in the 1930s. According to Otsuka and Wayman, Arne Ölander discovered the … See more how to roll a king palm
