Perruchoud, V.P. (author), Alderliesten, R.C. (author), Mosleh, Yasmine (author)Biobased fibre-reinforced polymer (FRP) composites, consisting of natural lignocellulosic fibres such as flax or hemp, are great alternatives to synthetic fibres to mitigate the environmental impact of high-performance composites in engineering structures. Natural fibres such as flax have damping and specific mechanical properties suitable to...journal article 2024

Zhu, Xuezhen (author), Zhang, Minghu (author), Shi, Jinyan (author), Weng, Yiwei (author), Yalçınkaya, Çağlar (author), Šavija, B. (author)High-strength engineered cementitious composites (ECC) typically require higher cement content, which is negative from the sustainability point of view. To alleviate this problem, herein a low-cost and eco-friendly high-strength ECC (with a compressive strength of over 100 MPa) was developed, and diatomite was used to replace a small amount...journal article 2024

Liu, Xu (author), Hu, D. (author), Li, Z. (author), Fan, Xuejun (author), Zhang, Kouchi (author), Fan, J. (author)The nano-copper particles are widely used in the sintering processes of packaging wide bandgap semiconductors. Despite the significant success in the industry, the mechanism bridging the sintering process to the mechanical properties of sintered nano-copper is not yet well-modeled. In this paper, the impacts of different sintering temperatures...conference paper 2024

Pimentel, Mário (author), Sine, Aurélio (author), Nunes, Sandra (author)The tensile response of ultra-high performance fibre-reinforced composites (UHPFRC) is decisive in many applications and depends on the steel fibre content and orientation. These vary troughout the structural element and may differ from those in the laboratory specimens used to characterize the material behaviour. This work presents the...journal article 2024

Shi, Zhanchong (author), Liang, M. (author), Su, Qingtian (author), Kanstad, Terje (author), Ferrara, Liberato (author)Rebar-reinforced coarse aggregate ultra-high-performance concrete (R-CA-UHPC) has been used in the construction of new structures and strengthening of deteriorated aged infrastructures, and it inevitably sustains tension. To study the tensile behavior of R-CA-UHPC members, axial tensile tests for dog-bone-shaped specimens were designed and...journal article 2024

Ulyanov, Boris (author)Liquid crystalline polymers have recently attracted attention for their great tensile properties. However, their interlaminar fracture toughness is low. To solve this, toughening approaches inspired by Nature are applied, exploiting the shaping freedom of fused deposition modelling. Three approaches are studied: the matchstick approach, z...master thesis 2023

Pouchias, Konstantinos (author)Lugs are a specific type of joint with a semi-circular geometry around the pinhole utilized in the aerospace field. Its distinct geometry and ability to carry loads in its plane make it a very common choice for design engineers. Although this type of joint is widely used, there are no analytical equations that can predict the stresses around the...master thesis 2023

Cheng, L. (author)In the past two decades, offshore wind has emerged as a new source of renewable energy. This highlights the requirement for the utilisation of larger and more efficient offshore wind turbines (OWTs). The connections used in support structures of OWTs are critical to ensure the excellent structural performance of OWFs. An alternative option is...doctoral thesis 2023

Koster, Jeroen (author)Aluminium alloy AA2024-T3 is a lightweight and damage tolerant material, and is therefore often used in aerospace applications. However, this alloy is difficult to weld using conventional fusion welding techniques due to defects caused by the meld pool.<br/> <br/>Friction stir welding (FSW) was developed by The Welding Institute (TWI) in 1991 in...master thesis 2023

RAMOS, STEPHANIE (author)Tensioned membrane structures are increasingly in demand, because of their ability to cover large spaces with minimum use of material. The material’s mechanical properties play a key role in the design of such structures. The shear behaviour is one of the main influential properties of woven textiles during complex deformations, such as the ones...master thesis 2023

Hamelers, Arthur (author)In a time of increasing awareness for the environment and rising energy prices, an efficiency in our material use is of paramount importance. This research is built on the notion that the design of light structures has a positive effect on the energy use of the built environment. The tent has been chosen to examine this approach of lightness in...master thesis 2023

Gaggero, M.B. (author), Esposito, R. (author)The brick-to-mortar bond often represents the weakest link leading to cracking and failure of masonry structures. For this reason, the in-situ characterization of masonry’s flexural bond behaviour (here defined as flexural bond strength and flexural bond fracture energy), is essential for the assessment of existing buildings. Among masonry...journal article 2023
