KraftLängen
KraftLängen is a term used in some German-language discussions of material deformation to denote a characteristic length scale associated with force-induced displacement. It is not an official SI quantity and does not appear in standard material-property catalogs. In simple terms, KraftLängen describes how much length a sample changes per unit of applied force, reflecting the material’s deformability under loading.
For a sample elongated along its axis by a force F, the change in length is ΔL.
Measurement and interpretation
To determine KraftLängen, a controlled force is applied to the specimen while precise length changes are recorded,
KraftLängen combines Kraft (force) and Längen (lengths) and is used mainly in teaching contexts or in informal
Stiffness, compliance, Young’s modulus, Hooke’s law, viscoelasticity.
