Modeling the tensile behavior of fiber bundles with irregular constituent fibers [PDF]

, 2004
In this paper, the effect of fiber dimensional irregularities on the tensile behavior of fiber bundles is modeled, using the finite element method (FEM). Fiber dimensional irregularities are simulated with sine waves of different magnitude.

Failure due to fatigue in fiber bundles and solids [PDF]

, 2003
We consider first a homogeneous fiber bundle model where all the fibers have got the same stress threshold beyond which all fail simultaneously in absence of noise.

Collective coordinates of the Skyrme model coupled with fermions

, 2003
The problem of construction of fiber bundle over the moduli space of the Skyrme model is considered. We analyse an extension of the original Skyrme model which includes the minimal interaction with fermions.

X-ray luminescence computed tomography using a focused X-ray beam

, 2017
Due to the low X-ray photon utilization efficiency and low measurement sensitivity of the electron multiplying charge coupled device (EMCCD) camera setup, the collimator based narrow beam X-ray luminescence computed tomography (XLCT) usually requires a ...

The refined transfer, bundle structures and algebraic K-theory

, 2007
We give new homotopy theoretic criteria for deciding when a fibration with homotopy finite fibers admits a reduction to a fiber bundle with compact topological manifold fibers.

Endoscopic optical coherence tomography with a flexible fiber bundle

, 2018
We demonstrate in vivo endoscopic optical coherence tomography (OCT) imaging in the forward direction using a flexible fiber bundle. In comparison to current conventional forward looking probe schemes, our approach simplifies the endoscope design by ...
