A functionally graded material beam with generalized boundary conditions is contemplated in the present study in order to examine the deformation and stress behavior under thermal and thermo-mechanical load. Three discrete combinations of functionally graded materials have been deliberate in including a wide range of materials and material properties. The variation of material properties has be...

INTRODUCTION Kinematic gait analysis via the multi-segmental Oxford foot model (OFM) may be a valuable addition to the biomechanical examination of the foot and ankle. The aim of this study is to assess the repeatability of the OFM in healthy subjects. METHODS Nine healthy subjects, without a history of lower extremity injury, were recruited. Markers were placed according to the OFM requireme...

Abstract The most widely-used representation of the compressible, isotropic, neo-Hookean hyperelastic model is considered in this paper. version under investigation that which implemented commercial finite element software ABAQUS, ANSYS and COMSOL. Transverse stretch solutions are obtained for following homogeneous deformations: uniaxial loading, equibiaxial loading plane stress, strain. ground...

BACKGROUND There is limited information regarding the mechanical factors contributing to the progression of posterior tibial tendon dysfunction. Therefore, an investigation of the mechanical forces on the posterior tibial tendon may improve our understanding of this pathology. METHODS The gliding resistance and excursion of the posterior tibial tendon in the retromalleolar region was measured...

The internal abdominal muscles are biaxially loaded in vivo, and therefore length-tension relations along and transverse to the directions of the muscle fibers are important in understanding their mechanical properties. We hypothesized that 1) internal oblique and transversus abdominis form an internal abdominal composite muscle with altered compliance than that of either muscle individually, a...

We report on the commissioning of a higher harmonic radiofrequency system at the Advanced Light Source, designed to improve the beam lifetime. We have achieved an increase above a factor of two in our best results up to now. Transient beam loading of the harmonic cavities, due to the unequal fill patterns, creates the greatest limitations on lifetime improvement. We also describe several intere...

We present experimental measurements of the peak splitting of the reflection spectra of fiber Bragg gratings as a result of birefringence induced by transverse loading of a multicore fiber. Measurements show that the splitting is a function of the applied load and the direction of the load relative to the azimuth of the fiber. A model for calculating the stress in the fiber that is due to an ap...

Advanced composites, particularly high modulus laminates, are often susceptible to transverse impact loading. Major damage introduced due to low velocity impact include matrix cracking, fiber break and delaminations. Such flaws tend to reduce residual strength of the material and may cause catastrophic failure when the material is subjected to higher operating loads [1,2]. Unfortunately, these ...

Although there is much data available on mammalian long-bone allometry, a theory explaining these data is still lacking. We show that bending and axial compression are the relevant loading modes and elucidate why the elastic similarity model failed to explain the experimental data. Our analysis provides scaling relations connecting bone diameter and length to the axial and transverse components...
