Axial and torsional stiffness of pediatric prosthetic feet

Clinical Biomechanics, 2017
Prosthetic stiffness likely affects the walking biomechanics of toddlers and children with leg amputations, but the actual stiffness values for prostheses are not reported by manufacturers or in standardized testing procedures.We measured axial (kA) and torsional (kT) stiffness from four brands of pediatric prosthetic feet (Trulife, Kingsley Mfg.

Contribution of the musculature to rotatory laxity and torsional stiffness at the knee

Journal of Biomechanics, 1987
The relationships between the mean rectified electromyogram (EMG) from two muscle groups crossing the knee joint and the rotational stiffness and laxity about the longitudinal axis of the lower leg were investigated. The EMG signals from three of the quadricep muscle group and two of the hamstring muscle group were monitored using surface electrodes ...

Torsional Stiffness of Embedded Footings

Journal of the Soil Mechanics and Foundations Division, 1971
Numerical values of torsional spring constants with corresponding stress and displacement distribution are obtained for circular footings for various embedment. The presence of rigid discs (thin rock layer), and voids (loose soil pockets), below the surface are considered, and torsional stiffnesses are obtained. The stress distribution around a footing

Study on Torsional Stiffness of Engine Crankshaft

2009 International Forum on Computer Science-Technology and Applications, 2009
Many empirical formulae are used to calculate torsional stiffness of Engine Crank, but discrepancy exists between these calculation results. In this paper, in order to obtain a more precise result, the modified Ker Wilson formula and Carter formula were employed to calculate torsional stiffness of engine crankthrow in the case of different thickness ...

The torsional stiffness of a shaft with an elongated slot

Strain, 1975
An analysis is given for estimating the torsional stiffness of a circular shaft with an elongated slot symmetrical about its centre line. The solution for the stress function is by a finite difference approach and because of symmetry, only one quarter of the cross–section is considered. A non–dimensional graph is presented of the ratio of the stiffness

Torsional stiffness of viscoelastic spheres in contact

The European Physical Journal B - Condensed Matter and Complex Systems, 2004
The theory of elastic contact between two spherical bodies according to Hertz, Mindlin and others is used as a basis for an extension to include the contribution of the viscous effects to the total stress for viscoelastic spheres subjected to twisting moments. Expressions relating twisting moment to the radius of a 'stick' region of the contact surface

Torsional Stiffness of Multicell Hollow Sections

Practice Periodical on Structural Design and Construction, 2001
Torsional stiffness is one of the member section properties commonly used in the 3D finite-element structural analysis. The explicit formulas for the torsional properties in both thin-walled open cross sections and single thin-walled closed sections, except for multicell closed sections, can be easily found in most textbooks and structural design ...

The experiment and analysis of torsion axle stiffness

2015 IEEE International Conference on Mechatronics and Automation (ICMA), 2015
Variation of tank torsion axle stiffness will appear along mileage increasing, and it will affect comfort and reliable durability of tanks. In this paper, the torsion axle stiffness is tested for two types of tank with various mileages, and the variation tendency of tank torsion axle stiffness is obtained.

On torsional stiffness and natural frequency of bellows

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004
Simplified formulae for torsional natural frequencies of bellows are developed using an equivalent thin-walled pipe model. To do this the torsional stiffness of bellows needs to be worked out. The torsional stiffness of bellows is determined using Chien's integration method.
