Explicit simulation and high-performance computing, application to a bolt tensile test
Résumé
The European project Maaximus (More Affordable Aircraft Structure Lifecycle through eXtended, Integrated & Mature nUmerical Sizing) aims at demonstrating the fast development and right-first-time validation of a highly optimized composite airframe. In this context, fasteners models are crucial to ensure correct structure modelling at a higher level. The present study focuses on a bolt tensile test. After a review of the state-of-the-art in this domain, the first part of the study is dedicated to explicit simulation and its specificities: resolution algorithm, mass and time scaling, comparison of energies. We also discuss about High-Performance Computing (HPC), and the need of consistency between model and computation structure. These simulation techniques are then applied to the modelling of the fastener tensile test. Experiments have been led with various fasteners diameters. We observe successful correlation between simulation and experiments both qualitatively and quantitatively.
