SUR LA DEFORMATION D'UN TUBE CYLINDRIQUE
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2010, Vol 55, Issue 1
Abstract
Une proposition de loi non-linéaire régissant le comportement des matériaux élastiques isotropes consiste souvent à généraliser la loi linéaire de Hooke, valable en petites déformations, par l’adjonction de termes supplémentaires afin de tenir compte d’effets du second ordre, du troisieme ordre, etc. Pour les matériaux incompressibles, les modèles se réduit à loi de Hooke en petites déformations.

ON A SHAPE IDENTIFICATION PROBLEM
An inverse method using a genetic algorithm and a quasi-Newton method is presented in this paper. We consider the problem of identifying a finite elastic airfilled hollow body of unknown shape embedded in a compressible,...
ASYMMETRICAL COLD STRIP ROLLING. A NEW ANALYTICAL APPROACH
In this paper is given a solution of asymmetrical strip rolling problem using a Bingham type constitutive equation and the perturbation method. Rolling pressure distribution, rolling force, rolling torque, front tension,...
INVARIANT CHARACTERIZING THERMALLY ACTIVATED PLASTIC FLOW
Thermal activation leads to a reduction of the flow stress below the athermal value (the zero Kelvin flow stress). The ratio between the flow stress at a given temperature and the athermal stress (at given material struc...
EXPERIMENTAL STUDY OF THE HEAT TRANSFER AND AIR GAP EVOLUTION DURING CASTING OF AN AC4CH ALUMINUM ALLOY
In the context of rapid changes of the technologies, casting becomes a manufacturing process of an increasing use. Therefore, the numerical methods and algorithms for solving heat conduction problems were extensively dev...
EIGENVALUE ANALYSIS OF CURVED SANDWICH PANELS LOADED IN UNIAXIAL COMPRESSION
An energy formulation of a simply supported cylindrically curved sandwich panel loaded in compression is introduced and the corresponding potential energy function is evaluated. The mechanical model of a cylindrically cu...
