Abstract
The purpose of this study was to evlauate and compare the effect of the variable factors of wire on the elastic properties of looped rectangular wire.
Five variable factors were presented - material(Hi-T, blue Elgiloy), wire size(.016" x .022", .018" x .025"), loop length(15mm, 20mm), loop configuration(open loop, closed loop), gabling (non-gable, gable). So, the total 256 specimens were divided into 32 groups, and each of those was pulled on Instron testing machine.
The load-deflection curve of each wire was obtained, Lrom which force, range in elastic limit, and stiffness were computed and analyzed statistically.
The results were obtained as follows :
1. All of the variable factors - wire material, size, loop length, loop configuration, and gabling - took a significant effect on load-deflection rate of looped wire.
The force at elastic limit was the smallest in the group of Hi-T, 0116´"x.022", 20mm loop length, open loop, non-gable, and the largest in the group of blue Elgiloy, .018´x.025", 15mm loop length, closed loop, non-gable.
g. The range at elastic limit was the smallest in the group of Hi-T, .018"x.025", 15mm loop length, open loop, non-gable, and the largest in the group of HI-T, .01&´x.022", 20mm loop length, dosed loop, gable.
4 Loop configuration and loop length were the most effective factors on the elastic properties of looped wires, and gabling was the least effective.
