The spine is routinely subjected to repetitive complex loading consisting of axial compression, torsion, flexion and extension. Mechanical loading is one of the important causes of spinal diseases, including disc herniation and disc degeneration. It is known that static and dynamic compression can lead to progressive disc degeneration, but little is known about the mechanobiology of the disc su...

This article is devoted to study the axial compression behaviour of recycled concrete-filled steel tubular (RCFST) columns after high temperature. Several members’ internal mechanisms are analyzed by combining experimental and finite element analysis (FEA). Firstly, failure mode members studied experiments. Then, based on correct constitutive relationship between concrete steel, model establish...

In this study, we investigated the depth-dependent metabolic and structural responses of adult articular cartilage to large-strain, static, unconfined compression. Changes in cell biosynthetic activity and several morphometry-based structural parameters (cell density, cell volume fraction, cell surface-area density, mean cell surface area, and mean cell volume) were measured at eight sites repr...

It is reported in the published literature that the resonant frequency of a silicon micromachined gyroscope decreases linearly with increasing temperature. However, when the axial force is considerable, the resonant frequency might increase as the temperature increases. The axial force is mainly induced by thermal stress due to the mismatch between the thermal expansion coefficients of the stru...

To increase understanding of damage evolution in advanced composite material systems, a series of large deflection bending-compression experiments and model predictions have been performed for a woven glass-epoxy composite material system. Theoretical developments employing both small and large deformation models and computational studies are performed. Results (a) show that the Euler–Bernoulli...

To realize the stability of the passive magnetic robotic system, a novel combination of permanent magnets is proposed. As we know, a single passive magnetic levitation is impossible to suspend all degrees of freedom of a rigid body; this article researches the combination of multiple passive magnetic bearings by the finite element method (FEM) simulation. Through changing the magnetization dire...

Title of Thesis: Failure Surface for L-shaped Reinforced Concrete Short Columns Mon-Chen Liu, Master of Science in Civil Engineering, 1983 Thesis directed by: Dr, C.T. Thomas Hsu Assistant Professor Department of Civil and Environmental Engineering Combined bending and axial compression for L-shaped reinforced concrete short columns is a common problem. But the present ACI Building Code (ACI 31...

klippel-feil syndrome is known by the classic triad of shortness of the neck , limitation of neck movements, and a low posterior hairline. there are often accompanying cervical spinal abnormalities such as kyphoscoliosis as well as urogenital and cardiac abnormalities. presented here we have a 20 year old young man with hypoesthesia and decreased motor function in the right hand. the problem be...

We describe the compression of a water-soluble polymer brush which undergoes compressioninduced phase transitions. The solution behavior of the polymer comprising the brush is described using the de Gennes “n-cluster” model which predicts a region of coexistence between dense and dilute phases. We show that compression of the brush can induce the formation of a dense coexisting phase or the eli...
