Damage detection and quantification via multiview DIC at varying scales

Résumé

Background: To minimize measurement uncertainties and create seamless procedures between tests and simulations for the characterization and prediction of damage in large scale structures, a system capable of monitoring the quantities of interest at different scales throughout the test is required. Objective: The aim of this work is to develop a multiview DIC framework at varying scales in which kinematic fields are expressed on a unique mesh. Methods: A three-point flexural test was performed on a concrete beam and the images acquired by three different cameras were used to perform DIC calculations. Results: Displacement and strain fields were measured using mono and multiview implementations; their associated uncertainties were assessed. Damage initiation and growth within the sample was quantified based on the standard displacement uncertainty. Conclusion: The reported results show that the proposed method reduced the associated displacement uncertainties. The onset and propagation of damage was successfully quantified.
