Sadowski, Adam Jan (author), Wong, W.J. (author), Li, Sai Chung Simon (author), Málaga-Chuquitaype, Christian (author)This article describes a dataset used to calibrate a finite element model of a thick circular hollow section (CHS) with varying d/t (diameter to thickness) ratio under cyclic loading which may be used as a computational model validation benchmark by researchers working on similar problems in structural and mechanical engineering. The test...journal article 2024

Yan, R. (author)High-strength steel (HSS) has higher strength but lower ductility than mild steel. The cross-section of the structural members may be reduced using HSS instead of mild steel, provided the buckling of elements does not govern the failure. The reduced member size benefits the environment and economy by means of less energy consumption, less carbon...doctoral thesis 2023

Tawfek, Abdullah M. (author), Ge, Zhi (author), Yuan, Huaqiang (author), Zhang, Ning (author), Zhang, Hongzhi (author), Ling, Yifeng (author), Guan, Yanhua (author), Šavija, B. (author)The mechanical performance of engineered cementitious composite (ECC) depends greatly on fiber orientation and distribution.

Zhang, F. (author), Yang, Y. (author), Hendriks, M.A.N. (author)Monitoring or identifying structural cracks is crucial for assessing the health of existing concrete structures. Key information about structural cracking encompasses the location of the crack and its kinematics, which include movements perpendicular and parallel to the crack face. Acoustic emission (AE) is a sensitive technique for detecting...journal article 2023

Schlangen, Miek (author), Schlangen, E. (author), van der Goot, Atze Jan (author)Mechanical properties of food products are regularly analysed by tensile tests. The aim of this study was to demonstrate the potential of using advanced tensile testing techniques to better understand the mechanical properties of anisotropic food products, such as meat analogues and certain dairy products. The effects of various tensile...journal article 2023

Lu, J. (author), Yang, Y. (author), van der Ham, H.W.M. (author), Fu, Danny (author)Geopolymer concrete is a new alternative material to conventional concrete with less carbon dioxide emissions. Researchers have reported much research on the material properties of geopolymer concrete. However, research on the behaviour of this newmaterial at the structural level is still limited, especially at a full-scale structural level....conference paper 2023

Li, X. (author)Fatigue damage of composite laminates has attracted considerable attention from research community and industry, in view that laminated structures are inevitable to suffer from fatigue loading during their service life. It is rather complicated to understand and explain, what governs the initiation, accumulation, interaction (synergy or...doctoral thesis 2022

Gijzenberg, Kees-Jaap (author)The goal of the thesis is to investigate two main questions for the purpose of modelling fractures in timber with a finite element method. The first question is to evaluate the use of digital image correlation during a three point bending test to obtain mean values for tensile strength and fracture energy, and the follow up question is if it is...master thesis 2022

Smeets, E.T.B. (author), Rans, C.D. (author), Alderliesten, R.C. (author), Castro, Saullo G.P. (author), Villegas, I.F. (author)Ultrasonic spot welding is a joining technique for thermoplastic composites with great potential regarding processing speed and cost. To investigate the damage tolerance and possible inherent damage arresting behavior of multi-spot welded joints, a technique is necessary to measure damage growth in the joints under cyclic loading. Visual...conference paper 2022

Yan, R. (author), Xin, Haohui (author), Yang, Fei (author), El Bamby, H. (author), Veljkovic, M. (author), Mela, Kristo (author)The heat-affected zone (HAZ) is an unmelted region of a welded joint that has changed in material properties because of high temperatures during the welding process. HAZ has a lower strength than the base (parent) material (BM) and the weld metal (WM). The lower material strength is more significant if BM is made of high strength steel and...journal article 2022

Hengst, Madusha (author)Atherosclerotic plaque rupture is the underlying cause of 50% of deaths in western society. Although screening methodologies exist, plaques are highly complex, and the parameters used to measure plaque vulnerability are often insufficient for correct medical screening. Since plaque rupture occurs when the vascular forces exceed the plaque...master thesis 2021
