ISSN: 1432-0924Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract We present an Element by Element (EBE) procedure to solve non symmetric linear systems arising from the solution of contact with friction problems. Hybrid formulation is introduced and different types of contact elements are reviewed. To deal with large scale problems the EBE method has proved to be a strongly parallel algorithm. Numerical experiments described in this paper confirmed the efficiency of this specific solver.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0924Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract In this paper we discuss the efficiency of two preconditioners (incomplete factorization and coarse/fine factorization) to solve non symmetric and ill-conditioned linear systems arising from the resolution of frictional contact problems. Mixed formulation is introduced and generalized Newton method is reviewed. We describe a multilevel interpolation adapted to the coarse/fine preconditioner. Numerical examples are proposed to show strong and weak points associated to both methods and optimal approximations are given to improve their efficiency.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0924Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract In this paper we present a numerical study of thin layers. This approach can modelise bonding phenomena or interfaces of composite materials. The considered layers have a hyperelastic behaviour. The study of the asymptotic problem, when the thickness and the rigidity parameters of the layer tend to zero, yields a limit problem with an interface law on the surface to which the layer shrinks. The limit problem keeps in memory the mechanical and geometrical properties of the layers in the sense that the relative behaviour of the limit values of stiffness and thickness of the layers appears in the interface law. By a numerical study of these problems, we aim to find quantitative conditions on the thickness in order to compare the results of the problem with an effective layer and those of the limit problems.Type of Medium: Electronic ResourceURL: -

ISSN: 1588-2780Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyEnergy, Environment Protection, Nuclear Power EngineeringNotes: Abstract The electrochemical reductions of hexavalent and tetravalent uranium are reported in γ-butyrolactone, γ-valerolactone, γ-octanoiclactone and in the mixed solvent γ-butyrolactone/tetrahydrofuran. The transient techniques foresee either the formation of uranium dioxide or uranium metal according to a two-step reduction but the presence of these cathodic products is difficult to ascertain in controlled potential electrolysis. While mixing a lactone with tetrahydrofuran, the reversibility of the electrode reactions increases. The conducting salt noticeably determines the current yield of uranium deposition. As additional kinetic phenomena are made clear, we found that sampled polarography is the best method to gain a full understanding of the electrode mechanisms.Type of Medium: Electronic ResourceURL:
