Abstract

Structural optimization problems aim at increasing the performance of the structure while decreasing its costs guaranteeing, however, the applicable safety requirements. As these aspects are conflicting, the formulation of the structural optimization problem as multiobjective is [...]

Abstract

In this paper we study the performance of two stochastic search methods: Genetic Algorithms and Simulated Annealing, applied to the optimization of pin‐jointed steel bar structures. We [...]

Abstract

The manufacturing process of a multi‐axial load cell requires robust tools to analyze the structural behavior when it is subjected to static and dynamic loads. In this work, it is given focus to the problem of optimizing a multi‐axial load cell model (6 load components) of [...]

Abstract

Conventional methods addressing the robust design optimization problem of structures usually require high computational requirements due to the nesting of uncertainty quantification within the optimization process. In order to address such a problem, this work proposes a methodology, [...]

Abstract

The design of reliable structures requires robust tools that allow the analysis of the behavior of the system subject to variability in its resistance and applied loads. For this, there are several formulations and computational algorithms that enable to model the structural behavior [...]

Abstract

This paper presents a method for shape optimization of two-dimensional models subjected to simple or multiple load cases. The optimization is performed iteratively using evolutionary rules, based on the stress level. These rules determine regions on the boundary where the material [...]
