 The study presents a family of topological systems called strained topological metamaterials, whose topological properties are revealed through higher-order coordinate transformations. The canonical mass dimer and a mechanical analog of the major anus supporting Ketayev chain are introduced as examples within this framework, extending the identification of topological edge states and promoting the fabrication of novel topological metamaterials with tailored boundaries.
