Biography
Professor Vincent Grolleau is a Senior Scientist at the Chair of Artificial Intelligence in Mechanics and Manufacturing (AIM) at ETH’s Department of Mechanical and Process Engineering (MAVT). He Splits histime between ETH Zurich in Switzerland and Université de Bretagne Sud, Lorient in France since 2017. He received the Agrégation in 1991, and completed his Master’s degree in Mechanics at Ecole Normale Supérieure Paris-Saclay. He obtained his Ph.D. from EcoleCentrale de Nantes in the field of metal cutting. His research interests focus on the development of new experimental techniques.
Presentation
“Novel and revisited experiments for plasticity and fracture testing of sheet metals”
Abstract
The modeling of material behavior for both plasticity and fracture requires the development of increasingly accurate tests. On the one hand, the development of DIC allows to revisit tests such as the bulge test or the in-plane torsion.On the other hand, recent results show the enormous value of using robotics to perform mechanical tests. The benefits are an unmatched combination of speed, reliability, and cost-effectiveness in generating a complete set of experimental data leading to afull characterization within months to days.
This presentation will illustrate some of these advances in automated plasticity and fracture tests, mini-Nakajima plane strain tensile tests with dihedral punch, in-plane torsion tests at different strain rates, constant strain rate bulge tests, and high throughput Nakajima tests.
