Reduced polynomial invariant integrity basis for in-plane magneto-mechanical loading

The description of the behavior of a material subjected to multi-physics loadings requires the formulation of constitutive laws that usually derive from Gibbs free energies, using invariant quantities depending on the considered physics and material…

Blind broad-band (0-10 Hz) numerical prediction of the 3-D near field seismic response of a Mw6.0 extended fault scenario: application to the nuclear site of Cadarache (France)

In this paper, physics-based numerical simulation (PBS) is employed to render a broad-band (0–10 Hz) realization of the near-field seismic response of the experimental nuclear site of Cadarache, located nearby the active Middle Durance Fault …

Validation of a new viscoelastic model for unidirectional polymer matrix composites by analytical and numerical homogenisation

The long-term response of unidirectional, fibres-reinforced, polymer matrix composites is affected by the viscoelastic behaviour of the matrix. Most composite models introduce a different relaxation function for each of the five elastic parameters…

Machine learning and micromechanics as allies to establish composition-property correlations in cement pastes

Composition-property correlations are fundamental to understand cement-based materials behavior and optimize their formulation. Modelling based on fundamental material component constitutes a reliable tool to establish these correlations with the…

The distance to cubic symmetry class as a polynomial optimization problem

Generically, a fully measured elasticity tensor has no material symmetry. For single crystals with a cubic lattice, or for the aeronautics turbine blades superalloys such as Nickel-based CMSX-4, cubic symmetry is nevertheless expected. It is in…

Distance to a constitutive tensor isotropy stratum by Lasserre polynomial optimization method

We give a detailed description of a polynomial optimization method allowing to solve a problem in continuum mechanics: the determination of the elasticity or the piezoelectricity tensor of a specific isotropy stratum the closest to a given…

A new Kalman filter approach for structural parameter tracking: application to the monitoring of damaging structures tested on shaking-tables

In this paper, a new data assimilation framework for correcting finite element models from datasets acquired on-the-fly in low-frequency dynamics is presented. An Unscented Kalman filter algorithm is coupled with a modified Constitutive Relation…

Tensile strength identification of remolded clayey soils

The tensile strength of soil is a major mechanical parameter controlling the development of tensile cracking, which is commonly encountered in many earth structures. This paper aims to identify the tensile behavior of different clayey soils. On one…

On the effect of concentration and wettability on polymer drops impact, dynamics and energy dissipation

The present study aims to understand the influence of small quantities of poly-ethylene oxide (PEO) diluted in pure distilled water with concentrations of 50, 100 and 200 parts per million (ppm) in the impact phenomenon of drops onto substrates of…

Eco-efficient concrete prepared with ternary slag cements

The cement and concrete industries have an urgent need to reduce their carbon emissions. Current reduction strategies are both insufficient and unsustainable. An emerging strategy is to prepare concrete with a reduced quantity of water and reactive…
