Zheng, Qinyi (author)Micro-indentation testing has shown great promise in extracting local mechanical properties of ductile metal materials. Although the relevant contact physics has been well revealed since the 19th century, interpreting the indentation data still poses many challenges at the application level. Regarding one of the mainstream methodologies for...master thesis 2024

Liang, M. (author), Xie, J. (author), He, S. (author), Chen, Y. (author), Schlangen, E. (author), Šavija, B. (author)Early-age cracking risk induced by autogenous deformation is high for cementitious materials of low water-binder ratios. The autogenous deformation, viscoelastic properties, and stress evolution are three important factors for understanding and quantifying the early-age cracking risk. This paper systematically reviewed the experimental and...review 2024

Lee, Michael (author)Summary<br/><br/>Numerous ancient historical constructions worldwide depend primarily on an extensive array of wooden foundation piles, as they are subject to loading conditions governed by the superstructure above. Wooden foundations transfer loads through a combination of compression and lateral resistance. The inherent strength of wood...master thesis 2023

SUN, Beibei (author), DING, Luchuan (author), Ye, G. (author), De SCHUTTER, Geert (author)In this paper, 871 data were collected from literature and trained by the 4 representative machine learning methods, in order to build a robust compressive strength predictive model for slag and fly ash based alkali activated concretes. The optimum models of each machine learning method were verified by 4 validation metrics and further...journal article 2023

Liang, M. (author), He, S. (author), Gan, Yidong (author), Zhang, Hongzhi (author), Chang, Z. (author), Schlangen, E. (author), Šavija, B. (author)This paper employs computer vision techniques to predict the micromechanical properties (i.e., elastic modulus and hardness) of cement paste based on an input of Backscattered Electron (BSE) images. A dataset comprising 40,000 nanoindentation tests and 40,000 BSE micrographs was built by express nanoindentation test and Scanning Electron...journal article 2023

Boersma, Emma (author)The osteochondral interface is known to smoothly mitigate the stress concentration over the surface area of the subchondral bone, with a structural transition from the cartilage to bone. These sites in the body are exposed to high forces, which makes them prone to failure. To improve the repair strategies, a better understanding of the...master thesis 2022

Zhang, Y. (author), Liang, M. (author), Gan, Y. (author), Copuroglu, Oguzhan (author)Slag rim mainly consists of secondary precipitations such as C–S–H gel phase and hydrotalcite-like phase, which originate from the hydration of slag. In this paper, the micro-mechanical properties of slag rim were characterized by nanoindentation in combination with SEM. It was found that, compared to the C–S–H gel phase, slag rim showed about a...journal article 2022

He, S. (author), Zhang, Shizhe (author), Lukovic, M. (author), Schlangen, E. (author)Strain hardening cementitious composite (SHCC) is a special class of ultra-ductile material which has autogenous self-healing capability due to its intrinsic tight crack widths. To further improve its healing ability, healing agent (HA) can be incorporated in SHCC, enabling it also the autonomous self-healing mechanism. In this study, the...journal article 2022

Wei, J.C. (author), Cartmill, Ian D. (author), Kendall, Mark AF (author), Crichton, Michael L. (author)With the development of wearable technologies, the interfacial properties of skin and devices have become much more important. For research and development purposes, porcine skin is often used to evaluate device performance, but the differences between in vivo, in situ and ex vivo porcine skin mechanical properties can potentially misdirect...journal article 2022

Inamdar, A.S. (author), Gromala, Przemyslaw Jakub (author), Prisacaru, Alexandru (author), Kabakchiev, Alexander (author), Yang, Yu Hsiang (author), Han, Bongtae (author)Epoxy molding compound (EMC) is widely used for encapsulating automotive electronics. Among all of the components of an electronic package, EMC is most exposed to the atmosphere, and thus undergoes aging. During high-temperature operation, EMC is oxidized, which alters its mechanical properties, and thus can affect the reliability of electronic...book chapter 2022

Rostami, R. (author), Klemm, A.J. (author)The use of Supplementary Cementitious Materials (SCMs) in concrete manufacture has significantly increased in the last decades mainly due to their sustainability benefits. Polymeric Fibres (PF) are commonly used in concrete in order to enhance adhesive and frictional bond with a cementitious matrix and improve mechanical properties. Despite...conference paper 2021

(author)Biofilm formation in membrane systems negatively impacts the filtration system performances. This study evaluated how biofilm compression driven by permeate flow increases the hydraulic resistance and leads to reduction in permeate flux. We analysed the effect of biofilm compression on hydraulic resistance and permeate flux through...journal article 2018
