Experimental and numerical tests were conducted under force control at different stress amplitudes in the high-cycle fatigue (HCF) regime. Based on the results, S–N curves were constructed, and the fatigue life of two auxetic geometries was determined. The numerical study was done using an elasto-plastic material model and stress-life approach to assess their fatigue life. The results showed that the tri-anti-chiral structure had a higher fatigue resistance compared to the tetra-anti-chiral structure. A good correlation was achieved between the numerical and experimental results, both in fatigue life predictions and in crack initiation regions. Additionally, a parametric study was conducted to assess the impact of modifying the node-strut junction radius on fatigue life.</dc:description><dc:publisher>Elsevier</dc:publisher><dc:date>2026</dc:date><dc:date>2026-03-19 15:12:23</dc:date><dc:type>Članek v reviji</dc:type><dc:identifier>97564</dc:identifier><dc:language>sl</dc:language></rdf:Description></rdf:RDF>
