Deformationsuntersuchungen

I’m not sure what term you want. “Deformationsun…” is incomplete and could refer to several concepts across fields (for example, deformation theory in mathematics, material deformation in physics or engineering, or a German term like Deformationsuntersuchung). Please provide the full term or specify the field and context you have in mind. If you’d like, I can also write a concise wiki-style article on one of these topics (for example, deformation theory in mathematics or deformation in materials science).
