SMA Torque Tube:
NiTi shape memory torque tube TIG welded to 304 stainless steel tubes lifting a load.
SMA Ribbon Embedded by UAM:
0.015 thick by 0.03" wide Shape Memory Alloy (SMA) Ribbon embedded in Aluminum matrix by Ultrasonic Additive Manufacturing (UAM).
Strain and Deflection of a Galfenol driven, unimorph micro-positioner:
The beam consists of a Galfenol layer bonded to a brass substrate. The substrate constrains the horizontal deflection of magnetostrictive Galfenol, causing vertical deflection of the composite beam.
Flux density in a Galfenol driven, unimorph micro-positioner:
The composite beam consists of Galfenol and brass layers. The brass substrate constrains the magnetostrictive Galfenol expansion, causing vertical deflection.
Microreeds modal analysis:
The first resonant mode of the square flap.
