Papoulidou, Sofia (author)The current structural demands include complex designs, efficient utilization of material resources, and maintenance of existing structures and infrastructure. In all these cases, the connections between structural components are the main focus of design since they are widely considered the weakest link in a structural system. The demand for...master thesis 2024

Smits, Coen-Jan (author)Increasing the efficiency of wind farms is important for speeding up the transition from fossil fuels to renewable energy sources. Current wind farm control relies on maximization of power generation of individual turbines. However, research has demonstrated that plant-wide wind farm control could optimize the performance of a wind farm. Wind...master thesis 2023

Westerbeek, Elise (author)Strain hardening cementitious composites (SHCC) can be used to reduce the amount of reinforcement needed to control crack widths. SHCC has a strain hardening behaviour with dense micro-cracking, which makes it more ductile compared to conventional concrete. Conventional concrete can be used in the non-critical locations. An interface is formed...master thesis 2023

Zhang, Shizhe (author), He, S. (author), Ghiassi, Bahman (author), van Breugel, K. (author), Ye, G. (author)This paper presents an experimental study on the interface bonding properties of polyvinyl alcohol (PVA) fiber in alkali-activated slag/fly ash (AASF) pastes. Three interface bonding properties (i.e., the chemical bonding energy Gd, the initial frictional bond strength τ0, and slip-hardening behavior) were determined using single-fiber pullout...journal article 2023

Zheng, T. (author), Guo, Licheng (author), Sun, Ruijian (author), Wang, Tongtong (author), Hong, Changqing (author), Benedictus, R. (author), Pascoe, J.A. (author)In this paper, the effect of interface properties on the compressive failure behavior of 3D woven composites (3DWC) is investigated by incorporating a micromechanics-based multiscale damage model (MMDM). The correlation between the mesoscopic stress of yarns and microscopic stress of constituents is established by defining a stress...journal article 2023

Mustafa, S. (author), Harrass, Othman (author), Lukovic, M. (author)The number of hybrid concrete structures is increasing due to the need for repairing/strengthening existing structures and the development of new hybrid concrete systems. The structural response of these hybrid structures might be governed by the strength of the interface between the two concretes, making it essential to characterize the...conference paper 2023

Golchin, A. (author), Guo, Y. (author), Vardon, P.J. (author), Liu, S. (author), Zhang, G. (author), Hicks, M.A. (author)The coupling effect of initial shear stress and thermal cycles on the thermomechanical behaviour of clay concrete and sand-concrete interfaces has been studied. A set of drained monotonic direct shear tests was conducted at the soil-concrete interface level. Samples were initially sheared to half of the material's shear strength and then they...journal article 2023

Zhang, Shizhe (author)Alkali-activated Materials (AAMs), including those classified as geopolymer, are obtained through the reaction between a solid precursor and an alkaline solution. Compared with ordinary Portland cement (OPC) binders, these materials maintain comparable mechanical properties but have the advantage of reducing greenhouse gas emissions and...doctoral thesis 2022

de Vos, Camill (author)While aramid fibre composites are generally said to have excellent impact properties, this has not yet been translated to the aerospace sector, where impact prone secondary structures remain to be made from metals or glass fibre reinforced polymer. Aramid fibre reinforced engineering thermoplastics could combine the stiffness of thermoset resins...master thesis 2022

Addi, Rhita (author)With the introduction of automated driving systems come benefits such as the improvement of traffic safety. However, with an increasing level of automation in vehicles also comes an increase in interaction with in-vehicle technology by drivers while they are meant to supervise the automated driving systems. Due to more interaction with in...master thesis 2022
