Topology optimisation for fluid flow and heat transfer applications
… we apply the two most prevalent topological optimisation algorithms to the design of single material heat sinks and heat exchangers. We aim to determine the merits and drawbacks of each method, extend the most suitable method to consider multi-material structures and to subsequently apply …

Evolutionary methods for topology optimisation of continuum structures: static and dynamic problems
This thesis studies the topology optimisation of continuum structures. Two methods have been investigated, namely. Evolutionary Structural Optimisation (ESO) and Bidirectional ESO (BESO). The basic concept of ESO is that by systematically removing inefficient materials from the structure, the …

Methods for designing the next generation of aircraft architectures using topology optimisation
… to conventional aircraft may not be applicable. Topology optimisation is the logical tool to employ in this type of situation, as its generality removes the need for any assumption of what the structure should be. Several barriers exist that stand in the way of topology optimisation’s use in …

Isogeometric Design, Analysis and Optimisation of Lattice-Skin Structures
… the geometric design, structural analysis and optimisation of lattice-skin structures is proposed in the dissertation. In the geometric design of lattice-skin structures, a novel shape interrogation scheme for splines, specifically subdivision surfaces, is proposed, which is able to compute the …

Structural fatigue assessment and optimisation of offshore wind turbine jacket foundations.
… generate innovative jacket designs by applying a topology optimisation algorithm. The research demonstrates the use of advanced computational techniques to improve existing designs by enhancing structural integrity and fatigue life whilst reducing the mass. The research presents a comprehensive …

Characterisation of a new nanostructured aluminium alloy and piston design for internal combustion engines
… in this work was to reduce piston mass using topology optimisation without affecting the external envelope and the shape of the combustion chamber. The new piston’s mass was 218.35 grams which was 16.38% lighter than the original piston with mass of 261.13 grams. The final machined piston …

Development of a design cycle for an additively manufactured aircraft rudder bracket
For traditional manufacturing processes, the variation of component quality and mechanical properties exists but these can be minimised by the implementation of process controls. Hence, it becomes key to define the full process for developing and manufacturing components. These processes have been …

Automated CAD Model Generation for Structural Optimisation
… finite element descriptions common in structural optimisation must be first translated into CAD models. Currently, this translation either can be performed semi-manually or fails to reserve the structural optimality found by the structural optimisation due to the intrinsic difference in geometric …

SPDE-derived random fields in structural optimisation and elastodynamics
… variability with applications on structural optimisation and statistical inference. Gaussian random fields on lattice structures are modelled by exploiting the established connection between random fields and stochastic partial differential equations (SPDEs). For a random field with Matérn …
