The effect of thermally induced stress on the modal properties of highly elliptical core optical fibers is studied in this work using a finite element method. The stress analysis is carried out and anisotropic refractive index change is calculated using both the conventional plane strain approximation and the generalized plane strain approach. After considering the stress optical effect, the mo...

t h r o u g h SEM and SAM Measurement of the fiber orientation is one of the most important inspection items 2.1 Orientation of the Molding Cross to examine the shape and strength of the Section through SEM products[ll. The 3D fiber orientation has been measured by analyzing the elliptical marks of the cross section of the fiber from the photograph of the FRP. In these methods, i t is not possi...

1. Abstract The aim of this work is to perform hierarchical optimization [1] in laminated composite structures, considering simultaneously macroscopic and microscopic levels in the design of the structure and its material. In the macroscopic level, the optimization algorithm cares with orientations and fiber volume fractions of unidirectionally reinforced composite material layers. In the micro...

Specific regulation and activation of focal adhesion kinase (FAK) are thought to be important for focal adhesion formation, and activation of Rho-kinase has been suggested to play a role in determining the effects of FAK on the formation of stress fibers and focal adhesions. To clarify the role of FAK in stress fiber formation and focal adhesion organization, the author examined the formation o...

To enhance the design process of high-performance woven fibers, it is vital to clarify evolution particle dendrites, dynamic pressure drop, and capture efficiency with respect dust loading during non-steady-state filtration process. A general element (orthogonal elliptical fibers) filter cloths numerically simulated using 3D lattice Boltzmann-cell automation (LB-CA) method, where gas dynamics s...

In the present research, the elastic buckling of composite cross-ply elliptical cylindrical shells under axial compression is studied through finite element approach. The formulation is based on shear deformation theory and the serendipity quadrilateral eight-node element is used to study the elastic behavior of elliptical cylindrical shells. The strain-displacement relations are accurately acc...

BACKGROUND The goal of this investigation was to correlate particular age-related structural changes (compaction) to the amount of scatter in rabbit lenses and to determine if significant fiber compaction occurred in the nuclear and inner cortical regions. METHODS New Zealand White rabbits at 16-20 months old (adult; n = 10) and at 3.5-4 years old (aged; n = 10) were utilized for this study. ...
