Simulation intent for multi-fidelity composite structural analysis

Abstract

This thesis presents novel methods for expanding Simulation Intent principles to develop an automated multi-fidelity modelling framework, which enables the automatic creation of local laminate failure analysis models embedded within a GFEM model. As Simulation Intent has not been applied without underlying CAD geometry, a key contribution is defining how equivalent relations are defined and suitable methods for automatic extraction to create an equivalent database, which robustly links different model fidelity representations for efficient model creation.

The thesis also presents case studies to understand the modelling fidelity required to capture damage and residual strength of local panels within a larger structure, such as an aircraft GFEM. Capturing the effects of the representative geometry and boundary conditions of the larger global structural assembly will enable further understanding of the effects of simulating representative structural environments on local laminate impact response and residual strength.
