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

Kementzetzidis, E. (author)At the end of 2019, the European Union (EU) put forward the European Green Deal to facilitate the technological progress necessary to achieve CO2-neutrality by 2050. Such a monumental achievement would require massive investments in infrastructure for the harvesting, storage and the transnational transportation of green energy. To date, the more...doctoral thesis 2023

Kementzetzidis, Evangelos (author), Pisano, F. (author), Elkadi, A.S.K. (author), Tsouvalas, A. (author), Metrikine, A. (author)Gentle Driving of Piles (GDP) is a new technology for the vibratory installation of tubular (mono)piles. Its founding principle is that both efficient installation and low noise emission can be achieved by applying to the pile a combination of axial and torsional vibrations. Preliminary development and demonstration of the proposed technology...journal article 2023

Li, Z. (author), Liu, Haoyuan (author), Hicks, M.A. (author), Pisano, F. (author)Offshore monopile foundations are exposed to misaligned wind and wave loadings, which are respectively dominated by (nearly) static and cyclic load components. While the response of these systems to unidirectional cyclic loading has been extensively investigated, only a few studies have been devoted to the realistic case of misaligned static...journal article 2023

Kementzetzidis, Evangelos (author), Pisano, F. (author), Metrikine, A. (author)The analysis of cyclically loaded piles is acquiring ever greater relevance in the field of geotechnical engineering, most recently in relation to the design of offshore monopiles. In this area, predicting the gradual accumulation of pile deflection under prolonged cycling is key to performing relevant serviceability assessments, for which...journal article 2022

Zhang, Zhihai (author), Xiao, Hong (author), Wang, Y. (author), Fang, Jia (author), Nadakatti, M. M. (author), Wang, Haoyu (author)The lateral resistance of ballast bed is an important parameter to prevent track expansion and maintain track stability. The invasion of sand particles can cause the change of lateral resistance of ballast bed and affect the stability of track structure, but little attention has been paid to the change characteristics of nonlinear lateral...journal article 2022

Kluge, C. (author), Blöcher, Guido (author), Hofmann, Hannes (author), Barnhoorn, A. (author), Schmittbuhl, Jean (author), Bruhn, D.F. (author)The hydraulic performance and mechanical stability of open fractures are crucial for several subsurface applications including fractured geothermal reservoirs or nuclear waste repositories. Their hydraulic and mechanical properties (fluid flow and fracture stiffness) are both strongly dependent on the fracture geometry. Any change in...journal article 2021

Fric, Nenad (author), Veljkovic, M. (author), Mišković, Zoran (author), Buđevac, Dragan (author)Slip-resistant shear connections with preloaded bolts have traditionally been used in steel structures exposed to cyclic / fatigue loading or in cases when bolt slipping or connection deformations should be restricted. Hence, shear load is transferred through friction surfaces rather than through contact between the bolt surface and the hole....journal article 2021

Igoe, David (author), Gavin, Kenneth (author)In recent years, there has been a significant push to develop optimized pile designs in the offshore industry, driven by the growth of offshore wind. One of the largest remaining uncertainties governing axial pile design in sands is the influence of ageing effects and how an aged pile responds under axial cyclic loading. This paper presents...journal article 2021

Kolken, H.M.A. (author), Garcia, A. Fontecha (author), Du Plessis, A. (author), Rans, C.D. (author), Mirzaali, Mohammad J. (author), Zadpoor, A.A. (author)Meta-biomaterials offer a promising route towards the development of life-lasting implants. The concept aims to achieve solutions that are ordinarily impossible, by offering a unique combination of mechanical, mass transport, and biological properties through the optimization of their small-scale geometrical and topological designs. In this...journal article 2021

Li, Q. (author)Although wind energy capacity has increased significantly in the last few decades, the installed capacity of offshore wind turbine still lags far behind that of onshore wind turbines due to the installation and foundation cost. The aim of this research project has been to clarify the influence of combined vertical and lateral loads, lateral...doctoral thesis 2020

Xu, Y. (author), Zhang, H. (author), Schlangen, E. (author), Lukovic, M. (author), Šavija, B. (author)Auxetic behavior refers to material with negative Poisson's ratio. In this research, a new type of cementitious auxetic material is developed. A novel crack bridging auxetic mechanism is discovered which is in contrast with a local buckling mechanism commonly employed to trigger auxetic behavior. Taking advantage of 3D printing techniques,...journal article 2020

Xu, Y. (author), Schlangen, E. (author), Šavija, B. (author)Mechanical behavior of cementitious cellular composites (CCC) with auxetic behavior was investigated under uniaxial compression and cyclic loading. Three cellular structures with different geometrical parameters are designed and prepared by 3D printing technique. Meanwhile, plain mortar and fiber reinforced mortar are used as constituent...book chapter 2020

Guo, Y. (author), Wang, Jianxi (author), Markine, V.L. (author), Jing, Guoqing (author)With the train speed and axle load increasing, excessive stresses are produced and transmitted to the ballast layer, inducing rapid ballast degradation. To solve this issue, the under sleeper pads (USPs) have been widely applied between sleepers and ballast particles as the elastic layer. In this research, laboratory tests using half-sleeper...journal article 2020

Zhang, F. (author), Yang, Y. (author)Acoustic Emission (AE) monitoring is one of the possibilities to detect the crack distribution inexisting concrete structures. However, the conventional method requires further destruction likeopening of new cracks or propagation of the existing cracks.
