On -Elastica

Shigeki Matsutani, Hiroshi Nishiguchi, Kenji Higashida +2

In this paper, we investigate a transition from an elastica to a piece-wised elastica whose connected point defines the hinge angle ; we refer the piece-wised elastica $Λ_{ϕ_0…

An algebraic description of screw dislocations in SC and BCC crystal lattices

Hiroyasu Hamada, Shigeki Matsutani, Junichi Nakagawa +2

We give an algebraic description of screw dislocations in a crystal, especially simple cubic (SC) and body centered cubic (BCC) crystals, using free abelian groups and fibering str…
