Analysis of the absorption energy for NiTi wires under different diameters and loop types
This paper presents the research undertaken at the University of Minho aiming to study the the behaviour of 3D weft-knitted structures using SMA wires and elastomers, in order to produce dynamic structures as a support to answer specific situations and applications. Several samples were produced using nitinol® wires in different diameters and loop types. The Tensile tests were carried out being based to NP EN ISO 2062:1993 standards, using a H100KS Hounsfield Universal Testing Instrument. The results showed that The 50μm wire showed to be too thin to this propose; moreover, The 210μm NiTi wire showed to be hard to process on the knitting machine due to its high stiffness; The 127μm NiTi wire showed to be the best among them, due to the process and energy absorption ratio. Finally, for both NiTi wires in different diameters studied, tuck loop showed to have the highest energy absorption capacity.
