Hybrid infrared-visible multiview correlation to study damage in a woven composite complex-shaped specimen

In this study, a cyclic tensile test on a notched butterfly specimen made of woven glass fiber composite was performed on a modified Arcan fixture. During the mechanical test, the sample was monitored with a hybrid stereoscopic system comprised of…

4D full-field measurements over the entire loading history: Evaluation of different temporal interpolations

Standard Digital Volume Correlation (DVC) approaches are based on pattern matching between two reconstructed volumes acquired at different stages. Such frameworks are limited by the number of scans (due to acquisition duration), and time-dependent…

Mesoscale DVC analyses and parameter calibration for pantographic block in 3-point flexure

In the present work, the mechanical response of a fiber network metamaterial was studied when subjected to 3-point flexure. To account for the initial deformation of the sample due to the fabrication process, backtracking (i.e., the nominal mesh was…

Physics-augmented neural networks for constitutive modeling: training with the modified Constitutive Relation Error

In the context of structural health monitoring (SHM), a novel approach is presented for learning con- stitutive laws using observable data. The proposed method utilizes a data-driven approach, employing a physics-augmented neural network to…

Non-intrusive electro-thermo-mechanical reduced model for diagnosis and prognostic on IGBT power modules

In this work, a reduced model based on the Proper Generalized Decomposition is developed to model the electro-thermo-mechanical of IGBT power module. The reduced model enables obtaining the solution to the coupled problem considering multiple model…
