In this work, fracture behavior of multilayered unidirectional graphite/epoxy composite (T800/3900-2) materials is investigated. Rectangular coupons with a single-edged notch are studied under geometrically symmetric loading configurations and impact loading conditions. The notch orientation parallel to or at an angle to the fiber orientation is considered to produce mode-I or mixed-mode (mode-...

This article proposes a sketch-based interface for modeling muscle fiber orientation of a 3D virtual heart model. Our target was electrophysiological simulation of the heart and fiber orientation is one of the key elements to obtaining reliable simulation results. We designed the interface and algorithm based on the observation that fiber orientation is always parallel to the surface of the hea...

This paper proposes a sketch-based interface for modeling muscle fiber orientation of a 3D virtual heart model. Our current target is electrophysiological simulation of heart and fiber orientation is one of the key elements to obtain faithful simulation results. The interface and algorithm are designed based on the observation that fiber orientation is always parallel to the heart surface. The ...

This paper deals with the problem of positivity preservation in numerical algorithms for simulating fiber suspension flows. In contrast to fiber orientation models based on the Advani-Tucker evolution equations for even-order orientation tensors, the probability distribution function of fiber orientation is approximated using the Galerkin discretization of the Fokker-Planck equation with Fourie...

The orientation of the fibers in UHPC is decisive for tensile strength and failure components. mold filling strategy during casting structural components dictates flow routing thus fiber orientation. In addition, also affects behavior suspension. measurements rheological properties concrete rheometers, strongly scattering often occur. this paper, a novel model viscoplastic fluids investigated C...

In this paper we study the dynamic behavior of a concentrated short glass fiber suspension subject to simple shear flow. In particular we are interested in determining the relationship between the stress growth functions (shear and first normal stress) and the evolution of the fibers’ orientation distribution within the sample. Stress growth experiments, in start-up of flow, are performed on a ...

A half-filling technique was demonstrated to improve the bending properties of a fluid-filled photonic crystal fiber. Such a technique can realize to fill selectively a fluid into half of air holes in a PCF. The bending properties of the half-filled PCF are quite different from those of the fully-filled PCF. Distinct bending properties were observed when the half-filled PCF was bent toward diff...
