Abstract
A torsional testing facility is described for the measurement of the delayed elastic (viscoelastic) and nonrecoverable (plastic) strains in materials in the region of 10-5 to 10-10 strain. The measurements obtained find applicability in the design and construction of large, diffraction-limited reflecting optics. Representative experimental data are presented.
