The feasibility of a thin-wire torsion stress-strain experiment with nanostrain sensitivity is demonstrated. A gauge length of 50 m was made possible by using The Monument, London, thereby restoring it to its original purpose as a scientific instrument. A wire of 150 μm diameter was studied using the load-unload method, and data were recorded in the elastic regime and through the elastic-plastic transition. Analysis of this preliminary experiment suggested some necessary improvements to the…

A new torsion tester based on an electronic autocollimator for characterizing the torsional behaviors of microfibers.

TLDR
A new torsion tester with high resolution is developed based on the torsional-balance method and the autocollimation principle for measuring the tORSional properties of single fibers and it is demonstrated that these fibers have a high anisotropy in mechanical properties.

Plasticity and thermal recovery of thin copper wires in torsion

Experiments in small-scale plasticity usually focus on small-sized samples. However, studying thin wires with lengths up to metres in torsion has the advantage of giving extremely high strain

Micromechanical testing with microstrain resolution.

Simple test equipment has been developed for studying the elastic limit and plastic deformation of thin metal wires and thin foils (down to 10 μm) under torsion, tension, and bending. Using

Elastic limit and strain hardening of thin wires in torsion.

TLDR
A theory for the size effect in the strength of wires under torsion is reported and compared with data from thin copper wires, implying that the physical principle is the constraint that size, whether grain size or structure size, puts on allowed dislocation curvature.

A new method to measure torsion moments on small-scaled specimens.

TLDR
A new method is presented, which allows determining torsion moments applied to wires as thin as 10 μm in monotonic as well as cyclic manner, and investigations on gold wires with diameters ranging from 10 to 60 μm, applying torsions in the nNm regime are shown.

Anomalous plasticity in the cyclic torsion of micron scale metallic wires.

TLDR
The plasticity of micron scale Cu and Au wires under cyclic torsions is investigated for the first time by using a torsion balance technique and a distinct Bauschinger effect and an anomalous plastic recovery are unambiguously revealed.

Quasi-Static Torsion Characterization of Micro-diameter Copper Wires

A method to measure very small torques that subject micro-diameter copper wires to plasticity is developed for quasi-static torsion experiment. Following the concept in the work by Fleck et al. (Acta
