Optimisation of welded beams: How cost functions affect the results

The increasing market competitiveness and CAE availability require the products to be optimised. This practice is exceedingly present when producing semi-standard parts like structural elements. Several cost calculation methods are developed, bringing up the question - which one to use? In this article, we compared three methods ; a welded I-section beam was used as an example. The optimisation was carried out using two objectives (mass and cost) and was submitted to Eurocode boundary conditions. The results have shown that the cost calculation method has a negligible influence on the results.
