Mechanical engineer and materials scientist Andy Lennon had used nitinol—a shape memory alloy of nickel ... create shape-changing structures that could be deployed in space applications.

That is, until Texas A&M researchers devised a way to use a shape memory alloy to do it. In addition to two different shape memory alloy configurations, the study looks at a more conventional ...

Shape Memory Alloys (SMAs) are unique materials that exhibit shape memory ... to complicated loading scenarios as well as advanced devices, such as porous SMA structures and self-healing composites, ...
