The Mechanics of Ribbons and Möbius Bands by Roger Fosdick, Eliot Fried

By Roger Fosdick, Eliot Fried

Recent advancements in biology and nanotechnology have motivated a speedily turning out to be curiosity within the mechanics of skinny, versatile ribbons and Mobius bands.

This edited quantity comprises English translations of 4 seminal papers in this subject, all initially written in German; of those, Michael A. Sadowsky released the 1st in 1929, by way of others in 1930, and Walter Wunderlich released the final in 1962.

The quantity additionally comprises invited, peer-reviewed, unique learn articles on similar topics.

Previously released within the magazine of Elasticity, quantity 119, factor 1-2, 2015.

The functional F (·, I ) defined by (18) is called the Sadowsky functional. 1 Existence of Γ -Limit In particular, following De Giorgi [6], given any sequence {εj } with εj > 0 and εj → 0 and any element u ∈ X: 1. for every sequence {uj } with uj ∈ X such that uj → u in X, F (u, I ) is bounded above in accord with F (u, I ) ≤ lim inf Fεj (uj , I ); (19) j →∞ 2. there exists a sequence {uj } converging to u such that F (u, I ) is bounded below in accord with F (u, I ) ≥ lim sup Fεj (uj , I ). (20) j →∞ For any such sequence {εj }, it is possible to extract a decreasing subsequence {εjk }.
