  • Method, apparatus and computer program product for modelling the non-linear structural response of a component
    Patent number: 9424687
    Abstract: A method, apparatus and computer program product for modeling the non-linear structural response of a component. The non-linear structural response is modeled using a two-step global-local finite element analysis method, which employs a linear global analysis step, a linear intermediate analysis step and a non-linear local analysis step. The boundary conditions applied in the intermediate step are derived in part from the linear global analysis and the boundary conditions applied in the local analysis are derived in part from the global and intermediate analyses.
    Type: Grant
    Filed: December 18, 2013
    Date of Patent: August 23, 2016
    Assignees: Airbus Operations Limited, Airbus Operations (SAS)
    Inventors: Shumit Das, Jean Philippe Navarro, Martin Kempeneers, Vincent Bozon
