In this article, a unified framework is introduced for robust structural topology optimization for 2D and 3D continuum and truss problems. The uncertain material parameters are modelled using a spatially correlated random field which is discretized u

This paper deals with the preliminary shape design of three-dimensional bridge structures. For crossing wide spans, lightweight truss structures are well-suited. Due to their complex equilibrium state involving a geometrically nonlinear behaviour, th

In a dynamic and evolving society there is a need for temporary and mobile structures. For this, deployable scissor structures – structural mechanisms that can transform from a compact state to a fully deployed configuration – are suitable. Howev

This paper addresses the problem of optimizing mechanical components during the first stage of the design process. While a previous study focused on parameterized designs with fixed configurations—which led to the development of the PAMUC (Preferen

In the design of mechanical structures, the evolutionary algorithms have taken a more and more important place, mostly because of their ability to explore widely the design space. Furthermore, as several objectives are often pursued simultaneously in

International audience; In this work, we highlight that sensitivity analysis of metal forming process requires both high precision and low cost numerical models. We propose a two-pronged methodology to address these challenges. The deep drawing simul

Multiobjective optimization using evolutionary algorithms (EA) has become a wide area of research during these last years. However, only a few papers deal with the handling of preferences. To take them into account, a method based on multi-criteria d
