Controlling the snap-through behavior of an elastica strip by cuts
Eszter Fehér
This work examines the snap-through behavior of a clamped-clamped elastica made from initially flat, thin, cut sheets under increasing vertical concentrated load acting at midspan.…
Quasi-static shape control of soft, morphing structures
Eszter Fehér, András Árpád Sipos, Péter Várkonyi
Inspired by biological systems, we introduce a general framework for quasi-static shape control of human-scale structures under slowly varying external actions or requirements. In…
Rigidity paradox of kirigami arches
Eszter Fehér
The geometry of bending-active kirigami arches, decorated by cuts and holes, is strongly influenced by the location and geometry of the perforations. This study demonstrates that,…
Resolving the evolution of natural fragment shapes
Balázs Havasi-Tóth, Eszter Fehér
We propose a geometrically motivated mathematical model which reveals the key features of coastal and fluvial fragment shape evolution from the earliest stages of the abrasion. Our…
