A methodology to estimate ventricular fiber orientations from in vivo images of patient heart geometries for personalized modeling is described. Validation of the methodology performed using normal and failing canine hearts demonstrate that that there are no significant differences between estimated and acquired fiber orientations at a clinically observable level.

Oriented Surfaces

A surface is called orientable if a consistent choice of unit normal vector can be made at every point on the surface. A thin soap film stretched across a wire loop provides a familiar example. The film separates the air on one side from the air on the other, so one side can be selected as positive and the opposite side as negative. Once this choice is made, a unit normal vector can be assigned smoothly across the entire surface.At each point on the soap film, a unit normal vector points...

In Vivo Single-Fiber Recording of Sciatic Nerve C-Fibers in Rats

2025
This video demonstrates a single-fiber recording of C-fiber nerve conduction in rats. An anesthetized rat is incised to expose the sciatic nerve, which provides sensory and motor supply to the lower limbs. The individual C-fibers are then exposed. Electrical stimulation is provided using stimulus electrodes implanted in the foot, and a response is recorded from a single nerve fiber.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Fiber-reinforced polymeric materials (FRP) are composite materials that are formed by longitudinal fibers embedded in a polymeric resin, thereby creating a polymer matrix with aligned fibers along one or more directions. In its simplest form, the fibers in FRP materials are aligned in an orderly, parallel fashion, thus imparting orthotropic material characteristics, meaning that the material...
FAQs
Mechanical response depends on the relationship between fiber direction and the applied load. The matrix transfers stress to the fibers, while the fibers carry the greatest stress along their length. As a result, a component can show different stiffness, strength, toughness, and dimensional stability in different directions, making orientation essential for predicting its behavior under service loads.
Alignment places the reinforcing fibers where they can carry a greater share of the applied stress along their length. This can improve the component's efficiency in that direction, whereas a different orientation changes how the matrix transfers load and can alter strength, stiffness, and failure behavior. Engineers therefore relate orientation choices to the directions of expected loading.
Changing orientation changes the directions in which the composite is most effectively reinforced. Because fibers carry stress most strongly along their length, selected arrangements influence where the material is stiffest, strongest, or more vulnerable under applied loads. Controlling these directions helps engineers manage failure behavior rather than treating the material as mechanically identical in every direction.
Layup, molding, winding, and flow through a tool can position fibers along selected directions during manufacturing. Each process provides a way to place reinforcement relative to the intended component geometry and loading conditions. The resulting arrangement affects how stress moves from the matrix into the fibers and therefore influences the finished part's mechanical performance.
Engineers tailor orientation rather than optimizing only one property. Selected directions can be used to control stiffness, strength, toughness, dimensional stability, and failure behavior within a component. This approach supports material-efficient designs because reinforcement is positioned according to the performance requirements of the structure, helping avoid a one-direction-only view of composite behavior.
Fiber orientation is important in lightweight aerospace structures, automotive components, wind turbine blades, sporting equipment, and civil infrastructure. In these applications, directional reinforcement helps engineers design around expected mechanical demands while accounting for anisotropic behavior. Orientation analysis also supports performance prediction and can improve material efficiency when components must deliver structural function with reduced weight.
