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…

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…

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…

Composite design bioinspired by the mesocarp of Brazil nut (Bertholletia excelsa)

The mesocarp of Bertholletia excelsa is a rich source of inspiration for strong, stiff and damage-tolerant composites. The bioinspired composites developed here are composed of an epoxy matrix with a 3D printed polylactic acid reinforced with 30% of…

Extraction of Implicit Knowledge and Optimization

Those last years have seen a growing maturity in optimization tools, particularly topological optimization [1]. Nevertheless, those methods do not take the accumulated knowledge of industrial manufacturers into account. Moreover, they face…

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…
