Abstract
28 Shape Memory Alloys (SMAs) are often used for robotic, biomedical, and
aerospace applications because of their unique ability to undergo large in a computer simulation that pinpointed the most likely cause of the
amounts of stress and strain during thermomechanical loading compared
to more traditional metals. While SMAs, such as NiTi has been used in wire
plate and tubular forms, NiTi as a woven dry fabric has yet to be analyzed
for use as protective materials and actuators. Applications of SMA fabric
as a “passive” material include shields, seatbelts, watchbands and window
screens. Applications as an “active” material include robotic actuators,
wearable medical and therapy devices, and self-healing shields and
screens. This paper applies a macro-mechanical model from a composites
analysis to NiTi plain woven fabric to determine the effective elastic
constants. The fabric model is based on actual weave geometry, including
the presence of open gaps and wire cross-sectional area, and with the
warp and weft the same diameter and alloy. A woven NiTi ribbon has been
manufactured using a narrow weaving machine and has been tested in
uniaxial tension and planar fabric constants were measured at a range of
temperatures. The analytically and experimentally derived constants for
various weave patterns and cover factor combinations are presented and
compared. It was determined that in uniaxial tension the fabric behaves
like a collection of unidirectional wires but is 78% less rigid, on average,
across all test temperatures. This result is predicted by the fabric model
with a 16% error, demonstrating that the proposed analytical model offers
a useful tool for design and simulation of SMA fabrics.
Biographies
Amanda Skalitzky from Kenosha, Wisconsin is currently pursuing her
master’s Degree in Mechanical Engineering at Auburn University. Her
research interests include Smart Materials and Woven Textiles. She has
recently been awarded the NASA Space Grant Fellowship where she will
continue her work under the direction of Dr. David Beale.
Austin Gurley is the co-founder and technical director at Deft Dynamics.
He holds a PhD in Mechanical Engineering from Auburn University, where
he studied as a NASA Space Grant Consortium Fellow. His research
interests include control and design of Shape Memory Alloy artificial
muscles and braided-lattice composites. During his time at Auburn he also
designed and taught a graduate course on ‘Embedded Systems in
Robotics’. As technical director at Deft Dynamics, LLC, he leads a team
inventing and designing in diverse fields from ultralight composites, to
data and sensing systems for race cars, to shape memory robots
and actuators.
r. Beale works in design and simulation of mechanical systems. He also
teaches the mechanical engineering senior project design experience
(capstone design), where students design and build a mechanical system
to a corporate sponsor’s design specifications. He has guided over 50
student project teams. He won a best paper award from the U.S. Army
Aviation Medical Association, which was based on a forensic engineering
study/accident investigation of a helicopter crash; the event was recreated
failure so that corrective action could be taken to prevent the failure from
occurring again. He has worked 4 years as an engineering analyst in
industry, applying FEA and mechanical system dynamic simulation
software (MSC-ADAMS), and developing software for computer simulation
of mechanical systems. His other industrial experience includes 1) 2 years
as a petroleum production engineer, responsible for the engineering of oil
and gas well workovers and surface processing equipment, 2) 2 years as a
piping engineer, designing pipe networks for steam, air, fuel and
