Toughness, degrees and 2-factors

چکیده
In this paper we generalize a Theorem of Jung which shows that 1-tough graphs with (G) |V (G)|−4 2 are hamiltonian. Our generalization shows that these graphs contain a wide variety of 2-factors. In fact, these graphs contain not only 2-factors having just one cycle (the hamiltonian case) but 2-factors with k cycles, for any k such that 1 k n−16 4 . © 2004 Elsevier B.V. All rights reserved.

متن کاملCeramic whisker reinforcement of dental resin composites.
Resin composites currently available are not suitable for use as large stress-bearing posterior restorations involving cusps due to their tendencies toward excessive fracture and wear. The glass fillers in composites provide only limited reinforcement because of the brittleness and low strength of glass. The aim of the present study was to reinforce dental resins with ceramic single-crystalline...
متن کاملNumerical Determination of Delamination Onset in Laminated Symmetric DCB Specimen
In this study, a novel numerical method is proposed for determination of mode-I interlaminar fracture toughness, GIc, in multi-directional (MD) double cantilever beam (DCB) specimens using fracture properties of unidirectional DCB specimens. Two factors, β and Dc are defined to minimize the undesirable effects on strain energy release rate. β describes the difference between maximum and average...
