Des. 2010;132(6):061007-061007-14. doi:10.1115/1.4001393 Figure Legend: T-latch operation cycle. The diagram illustrates the state of engagement, the T rotation angle ϕ, and the material phase of the wire (blue for martensite during engagement, retention, and reset, and red for austenite during release). The reset spring and upper plate are omitted from the diagram. The top row of diagrams shows side views while the bottom row shows top views.
