Torsional Vibrations in the Shafts of Linkage Mechanisms
Journal of Engineering for Industry, 1967Torsional vibrations in the input and output shafts of mechanisms are described by Hill’s differential equations. In this paper the equations are given and computer solutions, approximations, and the results of experiments are compared.

Torsional mechanisms in ductile building systems
Earthquake Engineering & Structural Dynamics, 1998It is postulated that in order to estimate torsional effects on the seismic response of ductile building structures, the associated plastic mechanism to be developed in the three-dimensional system should be identified. The proposed approach is very different from that embodied in building codes.

Torsional Fatigue and the Initiation Mechanism of Pilling
Textile Research Journal, 1980Torsional fatigue studies in polyester fibers have revealed that the fracture morphology of ruptured fiber surfaces is influenced by the level of torsional strain amplitude. At relatively high strain ampli tude the mechanism of fracture seems to be governed by the propagation of a single large crack.

Torsional mechanical filters at 500 kHz
IEEE 1988 Ultrasonics Symposium Proceedings., 2003A torsional mechanical filter configuration has been developed for operation in the commonly used IF (intermediate frequency) range of 500 kHz, utilizing third torsional-mode electromechanical transducer resonators in conjunction with second torsional-mode interior resonators.

Torsional vibration of shafts coupled by mechanisms
Journal of Sound and Vibration, 1987The paper is concerned with torsional vibration of a system composed of two parallel shafts coupled together by a number of mechanisms. The analysis has been done by using both non-linear and approximate linear equations. It is shown that there are three predominant sources of vibrations: (i) the tendency to different speed fluctuations of each ...

Torsional and biaxial (tension-torsion) fatigue damage mechanisms in Waspaloy at room temperature
International Journal of Fatigue, 1989Strain controlled torsional and biaxial (tension-torsion) low cycle fatigue behavior of Waspaloy was studied at room temperature as a function of heat treatment. Biaxial tests were conducted under proportional and nonproportional cyclic conditions. The deformation behavior under these different cyclic conditions was evaluated by slip trace analysis ...

Mechanical Behavior of Nylon Filaments in Torsion
Textile Research Journal, 1953The stress relaxation in torsion of 6,6-nylon filament is found to be nearly linear in the logarithm of time over periods from 20 to 20,000 sec. after twisting. On the basis of a generalized Maxwell model the behavior of the filament in free torsional vibration can be predicted from the results of the stress-relaxation experiments. The predictions were

Torsionally elastic vibration-damping mechanism
The Journal of the Acoustical Society of America, 1982A torsionally elastic vibration-damping and/or coupling mechanism has tor-transmitting, radial leaf springs, which at one end are gripped in an outer member and at the other end engage grooves of an inner member. To impart such a damping or coupling device a particularly long life by avoiding unfavorable friction conditions, rolling elements are ...
