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…

Compressibility and shear strength of a tropical fibrous peat

This study examines the compressibility and shear strength of an Indonesian fibrous peat through oedometric and consolidated undrained (CU) triaxial tests. The influence of fibres is considered by preparing two series of specimens – undisturbed and…

On a physics-compatible approach for data-driven computational mechanics

Within the framework of the thermodynamics of irreversible processes, one introduces a general vision of data-driven computational mechanics, adapted to history-dependent materials, through the concept of the “Experimental Constitutive Manifold” …
