Torsional impact of elastic spheres
Archive of Applied Mechanics, 1994The collision of two geometrically and materially similar elastic spheres, which are rotating around the common normal of their contact area, is analysed. The torsional rotation at the end of impact is obtained from numerical integration of the angular equation of motion and the contact law.

Torsion in Quadrupeds and Its Impact on Mammalian Joints
Clinical Orthopaedics and Related Research, 1994Congenital and acquired torsion occur in the limbs of domestic animals. Congenital abnormalities are of clinical significance in foals; they are also seen in calves whose dams have ingested certain toxic plants that contain teratogenic agents. Acquired torsional deformities are most common in foals, but are also observed in adult horses, dogs, and ...

Impact of fibular torsion and rotation on chronic ankle instability
Foot and Ankle Surgery, 2014The fibula is known not to involve in transmission of weight but known simply as an ankle stabilizer. However, its main function in stabilizing the ankle remains obscure. Since the fibula has an impact on torsion and rotation of the ankle, its effect on lateral ankle instability should be investigated.Twenty patients with lateral ankle instability ...

Impact of shaft torsionals in steam turbine control
IEEE Transactions on Energy Conversion, 1989Shaft torsional vibrations are discussed along with their effect on steam turbine-generator control following severe supply-network disturbances and the destabilization of shaft torsional modes through the action of high-speed electrohydraulic controllers.

Impact of Torsional and Bending Inertia on Root Canal Instruments
Journal of Endodontics, 2001The laws of applied mechanics can be used to analyze and predict the behavior of mechanical parts subjected to strain and distortion, such as endodontic instruments. Simple mathematical formulas can be used to represent the impact of torsional and bending inertias on stresses in endodontic instruments being used in root canals.

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 ...

Dynamic Modeling of Torsional Impact and its Stiffness Measurement for Impact Wrench
Volume 2: Diagnostics and Detection; Drilling; Dynamics and Control of Wind Energy Systems; Energy Harvesting; Estimation and Identification; Flexible and Smart Structure Control; Fuels Cells/Energy Storage; Human Robot Interaction; HVAC Building Energy Management; Industrial Applications; Intelligent Transportation Systems; Manufacturing; Mechatronics; Modelling and Validation; Motion and Vibration Control Applications, 2015Impact wrench is a popular hand tool whose mechanism is featured with impact characterized by short time duration and large contact torque. The nonlinear impact problem has drawn researchers’ interests for a long time and the investigation is still undergoing.
