vezelkrachten

Vezelkrachten, in Dutch, refer to the internal forces transmitted along fibers within a fibrous network or material. These forces arise when fibers experience tension due to external loads, active contraction, or interactions with a surrounding matrix, and they contribute to the overall stress state of the material. The forces tend to align with the fiber directions and can vary with fiber recruitment, orientation, and the mechanical state of the system.

In biological tissues, vezelkrachten are especially important for structures rich in collagen, such as tendons, ligaments, and the extracellular matrix. Collagen fibers carry a large portion of tensile load, and their orientation and recruitment dynamics determine tissue stiffness, resilience, and failure modes. Active tissues, like muscle-connected fibers, can also generate additional fiber forces through cellular or molecular contraction, adding to the passive mechanical response.

In materials science, the concept is central to fiber-reinforced composites and other anisotropic media. The macroscopic behavior is often modeled by decomposing stress into contributions from the matrix and the reinforcing fibers, with the latter carrying direction-dependent loads. The distribution of fiber orientations (the fiber orientation distribution) and the mechanical properties of individual fibers influence how vezelkrachten develop under load, affecting stiffness, strength, and damage progression.

Measurement and modeling approaches include experimental techniques such as polarized light methods and birefringence to probe fiber tension, as well as computational methods like finite element analysis that estimate fiber forces from observed deformations. These approaches help predict performance and guide design in engineering, biomechanics, and textile applications.
