Modeling the consolidation of fiber-reinforced thermoplastic composites at the part level presents a formidable computational challenge due to the multi-scale nature of the process. In this article, a method to bypass the multi-scale problem by homogenizing the micro scale and describing the medium with characteristic parameters is described....

This research provides a recommendation for Sonion, a company specialised in the development and production of hearing aids, on the production of moulds for the injection moulding machine. <br/><br/>The goal was to develop a process that reduces the cost and the time to manufacture an injection mould while maintaining a similar accuracy as in...

This graduation project argues for an alternative circular and healthy construction approach that can be applied to renovate other existing 1960s and 70s concrete buildings in the Netherlands. It integrates historic techniques such as press-fit timber connections, and uses natural and local harvested materials to provide the Hugo R. Kruytgebouw...

The accuracy of hot press forming process simulations with unidirectional fiber reinforced thermoplastics is not at the desired level. Fundamental knowledge about the interactions between adjacent plies is needed to enhance predictive quality. Several mechanisms can be distinguished during hot press forming of composites. This thesis focuses on...

Hot-pressing can be an attractive fabrication method that enables the forming of hybrid materials like thermoset based fibre metal laminates. However, the process simulation on press forming requires accurate material characterization and boundary conditions to facilitate part design for a defect-free component. In order to improve the overall...

The Organ on Chip (OoC) market is fast-growing and has the promise to drastically reduce the cost of developing drugs and the need for animal testing. However, the growth could be obstructed by the difficulties of scaling up production of developed prototypes. Most OoC prototypes are not suited for mass production because of the material used,...

Forming process with pre-stacked and uncured thermoset fibre metal laminate offers improved deformability compared to full-cured laminate especially for the production of complex structural components. This work investigated the friction behaviour at the metal-prepreg interface of glass fibre reinforced aluminium laminate through an inter-ply...

The present research was aimed at lowering the deformation temperature by applying cover tube casing (CTC) to AZ31 magnesium alloy samples subjected to equal channel angular pressing (ECAP) without triggering surface defects and/or fracture. The Cockcroft-Latham (C &amp; L) fracture model was incorporated into finite element simulation and...

This project deals with two problems, which in combination ask for a single solution. The first problem being plastic waste accumulation in low resource areas and the second being that production and construction materials in these low-resource areas are often very expensive. When these two problems are combined, an opportunity arises to...

de Hoop, J. (author)
Since post-consumer plastics have less well defined properties compared to virgin plastics they are not widely applied in consumer products. This thesis studied the unique qualities of post-consumer plastics. Tensile tests were performed, studying the impact qualities of recycled HDPE sheets. Leading to the optimisation of sheet production of...

A two-stage solution treatment composed of an initial soaking at 420 °C for 10 min and the second soaking at 500 °C for 10 min was applied to cold-worked AA6063 aluminum alloy samples after equal channel angular pressing (ECAP) for two and four passes. The microstructures and mechanical properties of the samples were compared with those of...

In this study, installation of jacked piles in sand is simulated using Press-Replace Method (PRM) and Material Point Method (MPM) and the results are compared together. This comparison is important because a realistic and yet efficient simulation of installation of jacked piles is an appealing step towards the design and analysis of this type of...

In this research, grain refinement through severe plastic deformation (SPD) in combination with a thermal treatment to create a fine initial grain structure with a high degree of supersaturation was taken as a viable approach to achieving simultaneous increases in the hardness, strength and ductility of the aluminum alloy AA6063 during...

Hot formed steels are witnessing an increasing use in safety critical and structural parts for automobiles due to their high strength, light weight and absence of springback, due to which understanding the corrosion behaviour of coated products for hot forming is crucial to increase their stronghold in Body-In-White (BIW) applications for...

In this work we report on generating/using simulated metabolite basis sets for the quantification of in vivo MRS signals, assuming that they have been acquired by using the PRESS pulse sequence. To that end we have employed the classes and functions of the GAMMA C++ library. By using several versions of our PRESS-simulation program, we were able...

The Skin of a shell structure is used a lot for roof structures, like domes and hypershells in de 60’s. Not very often the skin of the shell flows through the building and will create other transitions between interior and exterior. So the shell is not always a roof or only a thin enclosure. Skin and construction can be integrated or split up in...
