Features of a nano-twist phase in the nanolayered Ti3AlC2 MAX phase
Julien Guénolé, Vincent Taupin, Maxime Vallet +2
Complex intermetallic materials known as MAX phases exhibit exceptional properties from both metals and ceramics, largely thanks to their nanolayered structure. With high-resolutio…
An examination of local strain fields evolution in ductile cast iron through micromechanical simulations based on 3D imaging
Victor Manuel Trejo Navas, Ante Buljac, François Hild +3
Microscopic digital volume correlation (DVC) and finite element precoalescence strain evaluations are compared for two nodular cast iron specimens. Displacement fields from \textit…
Multifunctional properties of composition graded Al wires
Cui Yang, Nicolas Masquellier, Camille Gandiolle +1
The potentiality of composition graded AlMgSi wires for optimized combination of electrical conductivity and torsion strength has been investigated. Composition graded wires were o…
Adaptive reconstruction of imperfectly-observed monotone functions, with applications to uncertainty quantification
L. Bonnet, J. -L. Akian, É. Savin +1
Motivated by the desire to numerically calculate rigorous upper and lower bounds on deviation probabilities over large classes of probability distributions, we present an adaptive…
Modal features for image texture classification
Thomas Lacombe, Hugues Favreliere, Maurice Pillet
Feature extraction is a key step in image processing for pattern recognition and machine learning processes. Its purpose lies in reducing the dimensionality of the input data throu…
Dependency of the Young's modulus to plastic strain in DP steels: a consequence of heterogeneity ?
Ludovic Charleux, Laurent Tabourot, Emile Roux +2
The accurate springback prediction of dual phase (DP) steels has been reported as a major challenge. It was demonstrated that this was due to the lack of understanding of their non…
Contribution of field measurements in the study of composites reinforced with flax fibers during quasi-static tensile tests
Amélie Cuynet, Franck Toussaint, Emile Roux +2
This work is based on the study of the behaviour of flax fibres twill reinforced epoxy composites. The aim of the study is to determine the modulus of elasticity, Poisson coefficie…
Peculiar Rotation of Electron Vortex Beams
Thomas Schachinger, Stefan Löffler, Michael Stöger-Pollach +1
Standard electron optics predicts Larmor image rotation in the magnetic lens field of a TEM. Introducing the possibility to produce electron vortex beams with quantized orbital ang…
Two types of spurious damping forces potentially modeled in numerical seismic nonlinear response history analysis
Pierre Jehel, Pierre Léger
The purpose of this paper is to provide practitioners with further insight into spurious damping forces that can be generated in nonlinear seismic response history analyses (RHA).…
Review of the Synergies Between Computational Modeling and Experimental Characterization of Materials Across Length Scales
Rémi Dingreville, Richard A. Karnesky, Guillaume Puel +1
With the increasing interplay between experimental and computational approaches at multiple length scales, new research directions are emerging in materials science and computation…
On damping created by heterogeneous yielding in the numerical analysis of nonlinear reinforced concrete frame elements
Pierre Jehel, Régis Cottereau
In the dynamic analysis of structural engineering systems, it is common practice to introduce damping models to reproduce experimentally observed features. These models, for instan…
Initial versus tangent stiffness-based Rayleigh damping in inelastic time history seismic analyses
Pierre Jehel, Pierre Léger, Adnan Ibrahimbegovic
In the inelastic time history analyses of structures in seismic motion, part of the seismic energy that is imparted to the structure is absorbed by the inelastic structural model,…
Deformation mechanisms in a TiNi shape memory alloy during cyclic loading
Anne-Lise Gloanec, Giovambattista Billota, Michel Gerland
The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanis…
Boundary conditions and the dynamics of a dissipative granular gas: slightly dense case
P. Evesque
The effect of different possible kinds of motion of the exciting walls (cyclic, random, ...) is investigated on the dynamics of a granular dissipative gas. It is shown that the rea…
Microgravity and Dissipative Granular Gas in a vibrated container: a gas with an asymmetric speed distribution in the vibration direction, but with a null mean speed everywhere
P. Evesque
The main topic of this paper (part 4) is the interpretation of data from extended simulations published in previous Poudres & Grains (see P&G 17, #1 to #18) concerning the dynamics…
Granular Media under Vibration in Zero Gravity: Transition from Rattling to Granular Gas
P. Evesque, Y. Garrabos, G. Zhai +1
We report on different experimental behaviours of granular dissipative matter excited by vibration as studied during the 43rd ESA campaign of Airbus A300-0g from CNES. The effect o…
How one can make the bifurcation of Maxwell's demon in Granular Gas Hyper-Critical
P. Evesque
Experimental data from Maxwell's demon experiments on granular gas are revisited. It is shown that the transition nature changes from critical to sub-critical via a tri-critical po…
Optimisation de la taille de la série: illustration par un cas industriel de sous-traitance mécanique
Barbara Lyonnet, Maurice Pillet, Magali Pralus
Reducing costs of manufactured products is one of the key issues of companies. Bar turning companies (mechanical subcontracting companies) are faced with the following dilemma: use…
Identification of machining defects by Small Displacement Torsor and form parameterization method
Alain Sergent, Minh-Hien Bui, Hugues Favreliere +3
In the context of product quality, the methods that can be used to estimate machining defects and predict causes of these defects are one of the important factors of a manufacturin…
Computer Aided Tolerancing Based on Analysis and Synthetizes of Tolerances Method
Abdessalem Hassani, Nizar Aifaoui, Abdelmajid Benamara +1
The tolerancing step has a great importance in the design process. It characterises the relationship between the different sectors of the product life cycle: Design, Manufacturing…
