Suivi numérique des bifurcations pour l'analyse paramétrique de la dynamique non-linéaire des rotors
TL;DR: In this paper, a demarche combine, dans un premier temps, the methode de la balance harmonique (HBM) and the technique of bascule Temps-Frequence (AFT) is proposed to detect the bifurcations of branches de solutions periodiques of type point limite, point de branchement and notamment Neimark-Sacker.

SPH and ALE formulations for sloshing tank analysis
TL;DR: In this article, the mathematical and numerical implementation of the FEM and SPH formulations for sloshing problem are described, and it has been observed that for the SPH method to provide similar results as ALE formulation, SPH particle spacing needs to be finer than ALE mesh.
Journal ArticleDOI
Inelastic Behavior of Polyoxymethylene for Wide Strain Rate and Temperature Ranges: Constitutive Modeling and Identification.
TL;DR: The Drucker–Prager-type equivalent stress and the developed flow rule provide a better description of both the transverse and volumetric strains than that of the classical von Mises–Odqvist flow rules.
Finite element analysis of impact-perforated reinforced concrete slabs
TL;DR: In this article, a finite element analysis procedure for the impact analysis of reinforced concrete slabs under low-velocity and high-mass impacts using the Abaqus/Explicit solver is presented.

Computation of history-dependent mechanical damage of axonal fiber tracts in the brain: towards tracking sub-concussive and occupational damage to the brain
TL;DR: This work proposes a method for computing the history-dependent mechanical damage of axonal fiber bundle tracts in the brain through the introduction of multiple damage models, and provides the ability to link consecutive head impact simulations, so that potential injury to the brain can be tracked over time.

Journal ArticleDOI
Topology optimization of multi-material negative Poissons ratio metamaterials using a reconciled level set method
TL;DR: The proposed method simplifies the multi-material topology optimization by evolving each individual material with a single level set function and reconciling the result level set field with the MerrimanBenceOsher (MBO) operator.

How to characterize a nonlinear elastic material? A review on nonlinear constitutive parameters in isotropic finite elasticity.
L. Angela Mihai,Alain Goriely +1 more
TL;DR: Several nonlinear constitutive parameters, including the stretch modulus, the shear modulus and the Poisson function, that are defined for homogeneous isotropic hyperelastic materials and are measurable under axial or shear experimental tests are reviewed.
