A ground structure based topology optimization method for thermofluid problems

In this thesis, a ground structure based thermofluid topology optimization (TO) method is presented which is applicable to problems with creeping flow. Fluid channels with creeping flow are found in a variety of engineering applications, primarily in the field of microfluidics. Current fluid channel TO is typically done with density-based TO and...

Printing Reinforcement Steel: A study towards optimised, additive manufactured steel for reinforced concrete

In light of the global attempts to reduce material use by the construction industry, this research focuses on combining topology optimisation with additive manufacturing of steel. It is investigated whether an automated procedure can be developed to generate reliable strut and tie models for reinforced concrete elements, while satisfying the...

Topology Optimization of a Concrete Floor Slab Guided by Vacuumatic Formwork Constraints

This thesis presents a design for a topology-optimised concrete floor slab, of which the structural optimisation process is guided by manufacturability constraints from a vacuumatic formwork. The design has been obtained using an open-source, three-dimensional topology optimisation algorithm. Traditional floor systems are cost-optimised but can...

Overhang constraint in topology optimisation for additive manufacturing: A density gradient based approach

This research aims at improving the synergy between 3D printing and topology optimisation. 3D printing, more formally known as additive manufacturing, forms an object by constructing successive layers on top of each other. This procedure of manufacturing offers new possibilities due to the improved design freedom. Topology optimisation is a...

Topology Optimisation of Thin Membranes Applied on a Parafoil Rib

Membrane structures have a wide field of application in modern engineering due to their low weight-to-area ratio, which is especially exploited in kite design. The internal pressure of ram-air kites has to be well distributed over all cells in order to maintain the aerodynamic shape. By cutting holes in each rib the stagnated air can provide the...

Topology Optimisation of Metallisation Patterns in Photovoltaic Applications

Renewable energy is a trending topic nowadays. Government restrictions force us to produce less CO2 and use more renewable energy sources. One of the ways of becoming a more sustainable society is by using solar energy. Solar panels are promising in supplying a large part of our energy demand. The price per kWh is important to be competitive...
