Article
The building sector is responsible for more than 40% of the EU’s total energy consumption. To reduce the energy consumption in buildings and to achieve the EU’s fossil fuel saving targets for 2020 and beyond 2050, the energy efficient retrofitting strategies are critically important and need to be implemented effectively. This paper presents a dyna...

In this study, optimal shapes/profiles of axisymmetric continuum structures optimized for performance and manufacturability are sought, using a topology/shape optimization method called metamorphic development (MD). The optimization seeks to find an optimum cross-sectional profile and minimum weight design, subjected to von-Mises stress constraints...

A novel topology/shape optimisation method for axisymmetric elastic solids, based on solid modeling and FE analysis, is presented. Optimal profiles of minimum-mass axisymmetric structures are sought by growing and degenerating simple initial structures subject to response constraints. The rates of the growth and degeneration are controlled based on...

A multi-parameter optimization procedure for ultralightweight truss-core sandwich panels is presented in this paper. To satisfy high design requirements, the proposed approach incorporates objectives from various structural performances of the material system at many loading cases simultaneously. To determine an optimal topology of the truss-core p...

As an extension of the Evolutionary Structural Optimization [ESO] method, the bidirectional ESO [BESO] method has effectively addressed various topology optimization problems. It is observed in ESO/BESO applications that the optimal solution obtained strongly depends on the finite element mesh. This paper presents an improved BESO methodology incor...

Silicon- or silicon nitride-based microclips have recently been developed to hold optical fibres in micro-optical systems for high optical coupling efficiency. The fabrication process is simple, with one or two lithographic steps required on a thin film deposited on a silicon substrate. Single-mode optical fibres are inserted and held in position i...
