Residual torsional strength after impact of CFRP tubes
Composites Part B: Engineering, 2010This paper investigates the residual torsional strength of cylindrical T300-carbon/epoxy tubular specimens damaged by low-velocity impacts. A total of 24 specimens were subjected to a 7 J transverse impact under various torsional preloads. First, the torsional strength of four different lamination sequences is studied.

Saccular impact on ocular torsion
Brain Research Bulletin, 1996When someone is tilted laterally, the shear force on the maculae of the utriculus and the sacculus is described by the sine and the cosine of the angle of tilt, respectively. So both the sacculus and the utriculus are stimulated, but in the literature, ocular torsion is normally attributed to utricular function alone (and, thus, seen as a response to y-

Impact Response of Torsionally Coupled Base-isolated Structures
Journal of Vibration and Control, 2010The seismic response of a single-story asymmetric structure supported on various base isolation systems during impact with adjacent structures is investigated. Eccentricities arising due to elastic forces in the columns at the top-deck and the restoring forces in the isolation systems at the base-raft are considered.

Torsional Constraints of DNA Substrates Impact Cas9 Cleavage
Journal of the American Chemical Society, 2016To examine the effect of the torsional constraints imposed on DNA substrates on Cas9 cleavage, we prepared constrained DNA substrates using a DNA origami frame. By fixing the dsDNA at the connectors of the DNA frame, we created torsionally constrained or relaxed substrates.

Experimental study of torsional impact fatigue of shafts
Journal of Sound and Vibration, 2007Abstract This paper presents a methodology to study the fatigue strength of shafts under repeated impacts. The equipment for repeated impacts was designed for torsion tests of shafts for the same loading conditions as in service. The stress concentration effect, due to a fillet radius between square and circular cross-sections of the axle, was ...
