In geometry, the Weaire–Phelan structure is a three-dimensional structure representing an idealised foam of equal-sized bubbles, with two different shapes. In 1993, Denis Weaire and Robert Phelan found that this structure was a better solution of the Kelvin problem of tiling space by equal volume cells of minimum surface area than the previous best-known solution, the Kelvin structure.

  • En geometria, l'estructura de Weaire–Phelan és una estructura tridimensional complexa que representa una escuma idealitzada constituïda per bombolles de la mateixa mida. El 1993, el físic , del Trinity College de Dublín, juntament amb el seu estudiant Robert Phelan, van descobrir, en simulacions d'escumes per ordinador que aquesta estructura era una solució millor al "problema Kelvin" que la millor solució coneguda fins llavors, l'estructura Kelvin.

  • La estructura de Weaire-Phelan es una estructura tridimensional compleja. En 1993, y , dos físicos del Trinity College (Dublín), descubrieron que en simulaciones informáticas de la espuma, esta estructura era una mejor solución al "problema de Kelvin" que la otra solución conocida, la .​ (es)
  • En géométrie, la structure de Weaire–Phelan est une structure tridimensionnelle représentant la structure idéale d'une mousse de bulles d'égal volume. Ce réseau est constitué de polyèdres à faces courbes. En 1993, le physicien (en) du Trinity College (Dublin) et son élève Robert Phelan ont découvert grâce à des simulations informatiques que cette structure consistait en une meilleure solution du problème de Kelvin que la solution précédemment connue, la structure de Kelvin.

  • 幾何学においてウィア=フェラン構造(ウィア=フェランこうぞう、英: Weaire–Phelan structure)とは、等しいサイズの泡からなるフォーム(泡の集合体)を表す3次元構造の一種である。1993年、ダブリン大学トリニティ・カレッジの物理学者デニス・ウィア(en:Denis Weaire)とその学生ロバート・フェランは、フォームの計算機シミュレーションを通じて、この構造が「ケルヴィン問題」の最適解だと信じられていたケルヴィン構造より優れていることを発見した。 (ja)
  • In geometria, la struttura di Weaire–Phelan è una struttura tridimensionale complessa che rappresenta una schiuma ideale in cui le celle hanno stesso volume e stessa area della superficie esterna. Nel 1993, il fisico del Trinity College di Dublino e Robert Phelan (uno dei suoi studenti) scoprirono che, in una simulazione al computer, questa struttura rappresentava una soluzione al "problema di Kelvin" migliore di quella precedentemente conosciuta: la struttura di Kelvin.

  • 웨이어-펠란 구조(Weaire–Phelan structure)는 같은 부피의 거품을 최소의 면적으로 이룬다고 알려진 구조이다. (Denis Weaire)가 발견했다. 켈빈 남작 1세 윌리엄 톰슨(켈빈 경)이 예측한 깎은 정팔면체보다 약간 효율적이다. 현재 이것이 최적인지는 증명되지 않았다. (ko)

  • 在幾何學中,韋爾—費倫結構是一種較複雜的三維結構,其代表了大小相等的氣泡所形成的理想化泡沫結構之一。1993年都柏林大學三一學院的物理學家丹尼斯·韦尔和罗伯特·费伦用電腦模擬泡沫結構發現韋爾—費倫結構是克耳文問題裡比克耳文結構更好的解。這種結構被用於北京市国家游泳中心建築水立方的設計中。 (zh)
