In this paper, the rigid plastic finite element method is applied to analyze ring compression and the results are compared with those of the upper-bound method and experiments.

An organic coordination (complexing) compound in which the metal ion is bound to atoms of nonmetals, e. g. nitrogen, carbon, or oxygen, to form a heterocyclic ring having coordinate covalent bonds.

In mitochondria prohibitins mainly exist as membrane-bound ring complexes and function as chaperones maintaining mitochondrial protein stability during protein synthesis and transportation (3, 4).
