Reliability analysis and micromechanics: A coupled approach for composite failure prediction [PDF]

open access: yes, 2011
This work aims at associating two classical approaches for the design of composite materials: first, reliability methods that allow to account for the various uncertainties involved in the composite materials behaviour and lead to a rational estimation ...

Recent Advances in Colloidal Photonic Crystal-Based Anti-Counterfeiting Materials

open access: yesCrystals, 2019
Colloidal photonic crystal (PC)-based anti-counterfeiting materials have been widely studied due to their inimitable structural colors and tunable photonic band gaps (PBGs) as well as their convenient identification methods.

A General Bayesian Framework for Ellipse-based and Hyperbola-based Damage Localisation in Anisotropic Composite Plates [PDF]

open access: yes, 2015
This paper focuses on Bayesian Lamb wave-based damage localization in structural health monitoring of anisotropic composite materials. A Bayesian framework is applied to take account for uncertainties from experimental time-of-flight measurements and ...
