Structural health monitoring of beam-like and truss structures using frequency response and particle swarm optimization Ghent University
Robustness assessment and optimization of a simplified smart structure model for structural acoustic control KU Leuven
In the past 20 years, fundamental research has been conducted on intelligent materials towards developing smart structures. This has raised industrial interest for the application of smart structures to many problems found in civil life. Among those, noise is gaining an increased attention as it is one of the environmental pressures that most closely affects the EU citizens, as confirmed by public surveys on overall nuisance and health problems. ...
Compliance-based topology optimization of structural components subjected to thermo-mechanical loading Ghent University
Apart from mechanical actions, structural components in the construction industry may be subjected to a thermal gradient, causing (internally) restrained thermal expansion. These thermal loads can alter the mechanical response of components in a structural topology optimization procedure. Therefore, the influence of thermal loading should be considered in the sensitivity analysis to efficiently update the structural layout of material. In this ...
Density-based topology optimization of structural components considering temperature-dependent thermal and mechanical material properties Ghent University
Symmetry of solu- tions in discrete and continuous structural topology optimization Vrije Universiteit Brussel
In this paper a study is made of symmetry and asymmetry in structural topology optimization with discrete variables. A group theory approach is used to formally de ne the symmetry of the structural problems. This approach allows us to describe the set of symmetric structures and relate it to the entire search space. It is shown that, given a symmetric problem with continuous variables, an optimal symmetric solution (if any) exists. However, it ...
Symmetry and asymmetry of solutions in discrete variable structural optimization Vrije Universiteit Brussel
In this paper symmetry and asymmetry of optimal solutions in symmetric structural optimization problems is investigated, based on the choice of variables. A group theory approach is used to define the symmetry of the structural problems in a general way. This approach allows the set of symmetric structures to be described and related to the entire search space of the problem. A relationship between the design variables and the likelihood of ...
Design optimization for 3D concrete printing : improving structural and thermal performances Ghent University
This paper focuses on optimizing the shape of prefabricated building components that are produced using 3D concrete printing (3DCP) techniques. The proposed method is to improve the structural and thermal properties using heuristic optimization algorithms, as such that they meet the minimum standards determined by building design codes. First, a case study is constructed that is based upon an existing module design found in literature, and a ...
