Abstract: | We examine both the evolutionary structural optimisation (ESO) and solid isotropic microstructure with penalisation (SIMP)
methodologies by investigating a cantilever tie–beam. Initially, both ESO and SIMP produce designs with higher objective function
values relative to a previously published ‘intuitive’ design. However, after careful investigation of the numerical parameters
such as the initial design domain and the mesh size, both methods obtain designs that have lower objective function values
relative to the intuitive design. Thus, a clearer understanding of the numerical parame- ters and their influence on optimisation
methods is achieved. |
