Spannspannung

Spannspannung is not a standard term in mainstream German technical vocabularies. It is a compound that can be encountered in informal writing or in contexts where the words Spannung (which can mean either voltage in electronics or stress in mechanics) and the suffix -spannung are used without strict discipline. Consequently, Spannspannung is typically ambiguous and requires contextual clarification.

In a mechanical engineering or materials science context, Spannung denotes internal forces per unit area within a material. Common, well-defined terms are Zugspannung (tensile stress), Druckspannung (compressive stress), and Schubspannung (shear stress). The collective state is described by the Spannungstensor, with normal- and Schubkomponenten. A term like Spannspannung could be interpreted as a nonstandard shorthand for the overall stress state, but this usage is not typical in technical literature and is generally avoided in formal writing.

In an electrical engineering or electronics context, Spannung means voltage or potential difference. Here, Spannspannung would be unusual; standard terms refer to electrical voltage, voltage level, or breakdown-related quantities such as Durchbruchspannung (breakdown voltage) or Spannungspegel. If used, it should be clarified immediately to avoid confusion between mechanical tension and electrical voltage.

Overall, Spannspannung is not a recognized technical term with a fixed definition. When precision is required, authors should use Spannung in its proper domain (mechanical stress or electrical voltage) and, if needed, add descriptive qualifiers to prevent misinterpretation.
