Tolerance of the Cervical Spine to Eccentric Axial Compression

SAE Technical Paper Series, 2002
Cervical spine injury resulting from compressive impact loading is a particularly devastating musculoskeletal injury due to the frequency of neurologic involvement. The objective of this research was to investigate the effect of axial eccentricity on the tolerance of the cervical spine. Two functional spinal unit segments (3 adjacent vertebra and their

Nonlinear control of surge in axial compression systems

Automatica, 1996
This paper discusses the nonlinear control of a surge in axial compression systems. A nonliner model-based Luenberger-type observer is first developed from a simple incompressible flow model of an axial compressor rig; then the input-output feedback linearizing control technique is employed to derive an appropriate control law.

On the Buckling of Cylinders in Axial Compression

Journal of Applied Mechanics, 1973
The paper presents for the first time buckling results for cylinders in axial compression based upon shell equations advanced by Koiter and Budiansky. The numerical results are compared to those of Flu¨gge and of Donnell, and limiting results for the infinitely long shell are also given. The principal conclusion is that the Flu¨gge buckling results are

The Plastic Buckling of Axially Compressed Square Tubes

Journal of Applied Mechanics, 1992
A plastic buckling analysis for axially compressed square tubes is described in this paper. Deformation theory is used together with the realistic edge conditions for the panels of the tube introduced in our previous paper (Li and Reid, 1990), referred to hereafter as LR. The results obtained further our understanding of a number of problems related to

On the Buckling of Axially Compressed Imperfect Cylindrical Shells

Journal of Applied Mechanics, 1974
A theoretical investigation of the buckling behavior of imperfect isotropic shells with edge constraints and under axial compression was carried out. The nonlinear Donnell equations for imperfect isotropic shells have been reduced to an equivalent set of nonlinear ordinary differential equations.

Axial Compression Frame for MRI of Thoracolumbar Spine

American Journal of Roentgenology, 2007
Our objective was to present a method of performing thoracolumbar MRI with intervertebral disk pressure at 150 kPa without the patient being seated.Spine MRI with compression is more physiologic and will produce a higher yield than standard supine MRI.

Buckling of Axially Compressed Cylinders

Journal of the Structural Division, 1977
The results of buckling tests on 41 small-scale ring stiffened steel cylinders and one large radius fabricated ring stiffened steel cylinder under axial compression are presented. These results are compared with those of many other investigators on both stiffened and unstiffened cylinders.

Influence of Axial Length on Axially Compressed Aluminum Polygonal Tube

Materials Science Forum, 2018
Aluminum tubes are efficient energy absorbing components and are widely used in the automobile industry. In the previous report, the authors investigated the influence of cross-sectional shape on axially compressed aluminum tube by numerical analysis. However, there are only a few reports on length of aluminum tube.

Buckling of Circular Cones Under Axial Compression

Journal of Applied Mechanics, 1960
Presented are the results of an experimental investigation to determine the buckling strength of right circular cones under axial compression. Correlation of these data is made with existing theory and with previously published experimental data on circular cylinders; thus a recommended procedure for predicting the buckling load of right circular cones
