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…

Improving mechanical characteristics of a Zr based metallic glass under dynamic conditions by dynamic predeformation

The effects of dynamic predeformation on the dynamic behaviour of metallic glasses (MG) are investigated through split Hopkinson pressure bar (SHPB) tests. The results obtained on samples fractured in a single test are compared with those on samples…

Crack path and liquid metal embrittlement specificity of austenitic steels in mercury at room temperature

A liquid metal embrittlement specificity of three austenitic steels with increasing nickel content (304 L, 316 L and 316L(N)) is studied in liquid mercury in the axisymmetric notched geometry. Only the low nickel alloys are susceptible to LME. The…

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…

Analytical strain localization analysis of isotropic and anisotropic damage models for quasi-brittle materials

Strain and damage localization are usually precursors of rupture. We present a three-dimensional method dedicated to quasi-brittle materials based on the works of Bigoni & Hueckel, and Jirásek and coworkers, aiming at simplifying the analysis of…

Interfacial Cladding Engineering Suppresses Atomic Thermal Migration to Fabricate Well‐Defined Dual‐Atom Electrocatalysts

Abstract As an emerging frontier, dual‐atom catalysts (DACs) have sparked broad interest in energy catalysis, however the undesired thermal atomic migration during synthesis process pose significant challenge in enabling further applications. Herein…
