The Director of CIMNE, Prof. Eugenio Oñate, has actively participated at the 10th International Conference and Workshop on Numerical Simulation of 3D Sheet Metal Forming Processes, NUMISHEET 2016. The event, that has taken place in Bristol (UK) from 4th to 9th September, 2016, consists of a conference series established as a world-class forum through which new intellectual ideas and technologies in the area of sheet metal forming simulation are exchanged.
Prof. Oñate participated at two conference lectures on Tuesday 6th September. During the morning, he gave a Plenary Lecture entitled A Triaxial Failure Diagram to predict the forming limit of 3D sheet metal parts subjected to multiaxial stresses: Fernando Rastellini, Scientist at CIMNE; and Gerardo Socorro and Albert Forgas, managers of GUI and Business Development, respectively, at Quantech ATZ. The paper proposes a new failure criterion based on the stress triaxility and the effective plastic strain accumulated during the history of material loading. This method allows an accurate prediction of failure and forming limits, essential at modelling sheet metal forming processes.
The Director of CIMNE also gave a speech at one of the Plenary Sessions of the event and, during the afternoon, took part at the conference lecture Advances in the finite element for sheet metal forming processes. It was presented by Vicente Mataix Ferrándiz, PhD Student at CIMNE, Riccardo Rossi, Full Research Professor at CIMNE, Fernando Flores, Full Professor at FCEFyN and researcher at CONICET, co-authors of the paper Advanced solid elements for sheet metal forming simulation.

The NUMISHEET conference in Bristol, UK, featured technical, keynote, plenary sessions and mini-symposiums in diverse sheet metal forming areas including the recently introduced incremental sheet forming and electromagnetic forming, as well as new prominent numerical methods such as IsoGeometric analysis and meshless methods for sheet analysis. One of the most distinguishing features of NUMISHEET conference series is the industrial benchmark session, during which numerical simulations of industrial sheet formed parts are compared with experimental results from the industry. The benchmark sessions provided an opportunity for networking, for the exchange of technologies related to sheet metal forming and for the numerical validation of sheet metal forming codes.
The conference proceedings include standard proceedings for regular and keynote papers and a separated proceedings for the industrial benchmarks. Both proceedings are published by the Institute of Physics (IOP) and included in SCOPUS database for a wide scientific dissemination.
