| dc.description.abstract | Shape optimisation is a nowadays-standard requirement in the design of lightweight structural components. In this paper, optimisation of I-beam cross-section of integral aluminium 2024-T3 wing spar is presented, taking the maximum fatigue life as the criterion. Toward this aim, the extended finite element method (XFEM) was used to simulate crack growth in complex I-beam geometry. The computations were carried out using Morfeo/Crack add-on based on XFEM implementation in Abaqus software. Fatigue lives of wing spars with different sizes of cross section but constant area were compared. Conducted analysis has shown that XFEM seems to be efficient tool for complex three-dimensional configurations optimisation. | en |
