Concrete drying kinetics: development of an accelerated drying protocol in fire testing

The fire behavior of concrete is a critical aspect in the context of civil engineering works for which, in most cases, fire characterization tests are required. Concrete spalling is strongly dependent on the hydric state and material permeability…

Numerical and experimental investigation of wall effect in concrete

This study presents a new numerical approach using tools developed to perform a molecular simulation to investigate the wall effect on aggregates and mortar distribution in concrete. Aggregates are represented by spheres interacting via a…

Improved EBSD indexation accuracy by considering energy distribution of diffraction patterns

Registering experimental and simulated electron diffraction patterns is increasingly used for advanced electron backscatter diffraction indexation (EBSD) analysis, yet the accuracy of registration is limited by several effects not accounted for in…

Weakly-invasive LATIN-PGD for solving time-dependent non-linear parametrized problems in solid mechanics

A weakly-invasive version of the LATIN-PGD method is introduced to compute reduced-order models in solid mechanics for time-dependent non-linear parametrized problems under quasi-static assumption. Its main interest is to be easily implemented in…

On the stability of POD Basis Interpolation via Grassmann Manifolds for Parametric Model Order Reduction in Hyperelasticity

This work considers the stability of Proper Orthogonal Decomposition (POD) basis interpolation on Grassmann manifolds for parametric Model Order Reduction (pMOR) in hyperelasticity. The article contribution is mainly about stability conditions, all…
