Method, apparatus and computer program product for modelling the non-linear structural response of a component

摘要

A method, apparatus and computer program product for modelling the non-linear structural response of a component. The non-linear structural response is modelled 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.
