Abstract: The innovation presented herein provides among its embodiments, a non-pneumatic structure such as a vehicle tire, consisting of a matrix of shape memory alloy (SMA) elements. The interlocking layering pattern provides geometries which leverage the SMA material properties to accomplish performance characteristics of traditional pneumatic structures across a spectrum of possible desired uses including normal personal use, recreational use, sport use and commercial use. Embodiments include applying structural design and material properties to provide a fixed or a variable set of performance characteristics. Similar to the fruits of other space program initiatives, the innovation leverages material science developed for extra-terrestrial purposes to accomplish advances over conventional items.
