Continuous anisotropic damage as a twin modelling of discrete bi-dimensional fracture

In this contribution, the use of discrete simulations to formulate an anisotropic damage model is investigated. It is proposed to use a beam-particle model to perform numerical characterization tests. Indeed, this discrete model explicitly describes…

Integrity bases for cubic nonlinear magnetostriction

A so-called smart material is a material that is the seat of one or more multiphysical coupling. One of the key points in the development of the constitutive laws of these materials, either at the local or at the global scale, is to formulate a free…

A Non-Intrusive Space-Time Interpolation from Compact Stiefel Manifolds of Parametrized Rigid-Viscoplastic FEM Problems

This work aims to interpolate parametrized Reduced Order Model (ROM) basis constructed via the Proper Orthogonal Decomposition (POD) to derive a robust ROM of the system's dynamics for an unseen target parameter value. A novel non-intrusive Space…

Highlighting the role of heterogeneity on the indentation hardness of foamed gypsum

The objective of this work is to link microstructure features of foamed gypsum (lightweight gypsum board core material) and its compressive properties. Several samples of foamed gypsum with different microstructures were manufactured and…

Development of a digital twin of the sensing coil of fiber-optic gyroscope under homogeneous thermal field compared with Rayleigh-OFDR measurements

We propose a digital axisymmetric thermomechanical model of the sensing coil of fiber-optic gyroscope to compute the strain along the fiber. Validity and limitations of this model are evaluated using Rayleigh-OFDR measurements.
