Wang, L. (author), Li, Erlei (author), Zhou, Zongyan (author), Zhang, Baicheng (author), Yu, Aibing (author)Powder bed fusion additive manufacturing has been applied to the fabrication of functionally graded materials. A new design that allows the material composition to change along the direction perpendicular to the powder spreading has been reported in the literature. Based on this design, this work examines the quality of the graded spread...journal article 2023

van Duijvenbode, J.R. (author), Soleymani Shishvan, M. (author)The results of dig limit delineation in open pit mining are never truly optimized due to gaps in the underlying data, such as insufficient sampling. Aside from the data uncertainty, there is also an influence on the final dig limit by either humans or by the heuristic character of an optimization method like simulated annealing. Several dig...journal article 2022

Baartman, Wesley (author)In this thesis, we have defined a symbolic execution technique to automatically generate test suites for programs written in functional programming languages that can find the behavioural differences between a reference implementation and a set of potentially different implementations. Our symbolic execution technique uses a constraint solver in...master thesis 2022

Schimmel, Jim (author)Wire Arc Additive Manufacturing (WAAM) uses an arc welding process and consumable filler wire to deposit near net shaped 3d structures in a layer by layer manner. The highly flexible nature of the process enables the production of components with materials that are otherwise challenging to process using subtractive manufacturing methods. Invar...master thesis 2022

Terol Sanchez, María (author)This study addresses the effects of additive manufacturing (AM) parameters and post-processing heat treatments on the microstructure and fracture toughness behavior of functionally graded and non-graded Inconel 718. Laser powers of 250W and 950W were used to fabricate non-graded and graded specimens. To study the effects of the microstructural...master thesis 2022

Kuipers, T. (author)The products in our day to day lives have different requirements in different regions of the product. One way of dealing with such spatially varying requirements is to divide the product into multiple parts and assign each part a different material. For example, the handle of a drill is often fitted with a rubbery material which gives it more...doctoral thesis 2022

Pei, Zhongshi (author), Xu, Meng (author), Cao, Jiwei (author), Feng, Decheng (author), Hu, Wei (author), Ren, Junda (author), Jing, R. (author), Yi, Junyan (author)Asphalt aging often leads to rapid degradation of road performance, which seriously affects the service life of asphalt pavement. Exploring the influence of asphalt oil sources, asphalt grades, and filler types on asphalt microcharacteristics in the asphalt aging process can provide an essential reference to guide asphalt pavement maintenance...journal article 2022

Westermayr, Maximilian (author), Zeilhofer, Monika (author), Rais, Andreas (author), Kovryga, Andriy (author), van de Kuilen, J.W.G. (author)The market share of European beech (Fagus sylvatica L.) wood in the construction sector is low despite an increase in beech stock in Central European Forests in recent years. More efficient sawing techniques, higher lamella grading yields and solving of adhesion challenges may increase the competitiveness of beech glulam and promote its use....journal article 2022

Xu, Y. (author), Zhang, H. (author), Gan, Y. (author), Šavija, B. (author)Cementitious materials are widely used in construction. For their low ductility, they typically need to be reinforced by steel rebars, which cause potential corrosion problems. Polymeric reinforcement, which does not have corrosion problems, has been used to replace steel rebars. However, a relatively high reinforcing ratio is usually...journal article 2021
