Redondo Garcia, Elara (author)The level of advancement in the understanding of the mechanical properties of volcanic rocks is comparatively lower than that of sedimentary rocks. As part of the SUCCEED Project (Synergetic Utilisation of CO2 Storage Coupled with Geothermal Energy Deployment), which aims to investigate the feasibility of injecting captured and produced CO2 into...master thesis 2023

Zwarts, Sijmen (author)The first part of the thesis explores the process of homogenization, particularly for the permeability properties of rock samples. The Hill-Mandel postulate of energy consistency throughout the transitioning of scales is revisited since traditional homogenization methods rely on applying specific boundary conditions to enforce energy consistency...master thesis 2023

Janssen, M.T.G. (author), Draganov, D.S. (author), Barnhoorn, A. (author), Wolf, K.H.A.A. (author)As part of a seismic monitoring project in a geothermal field, where the feasibility of re-injection and storage of produced CO<sub>2</sub> is being investigated, a P- and S-wave seismic velocity characterisation study was carried out. The effect of axial and radial (up to 42 MPa) stress, pore pressure (up to 17 MPa), pore fluid (100% brine...journal article 2023

A state-of-the-art review of Natural bitumen in pavement: Underlining challenges and the way forwardAnupam, K. (author), Akinmade, O.D. (author), Kasbergen, C. (author), Erkens, S. (author), Adebiyi, Festus (author)The demand for alternative bitumen which could fully/partially replace Petroleum sourced bitumen for pavement construction is globally increasing. The increase in demand can be associated with several factors: depletion in crude oil resources, advances in crude oil refining processes, increased demand for highway infrastructure, and regional...review 2023

Li, Jianguo (author), Wang, Bin (author), Wang, Di (author), Zhang, Pei (author), Vardon, P.J. (author)Aiming at modelling the mechanical behaviour of soil-rock mixtures accurately and efficiently, a coupled MPM-DEM formulation combining the material point method (MPM) and the discrete element method (DEM) is proposed. It is solved concurrently via the contact force linking the two individual methods. Specifically, the soil is modelled with...journal article 2023

Vehmeijer, Reinoud (author)Subsea rock installation is a process in offshore engineering where rocks are placed on the seabed or subsea structures using a fallpipe. An example of a subsea structure could be a cable or pipeline that must be protected. In this research, the main scope is rock installation for scour protection of the foundation of offshore wind turbines. As...master thesis 2022

Kleisiaris, Georgios (author)The need for sustainable solutions in the energy sector has led to the rapid increase of offshore windfarms around the globe. The areas with ideal soil conditions are gradually being occupied, pushing the offshore wind industry to search for methods of installing wind turbines in hard terrain. So far, the installation of monopiles in weak rock,...master thesis 2022

Luijten, Tim (author)Starting in the 1930’s, many research projects have been performed with the intent to establish rules, which can be used to design granular, geometrically closed filter structures for hydraulic structures. However, for the vast majority of these research projects, the filter structure was loaded by uniform flow, either in the parallel or...master thesis 2022

Zijlstra, Maarten (author)The dolmens erected in the province of Drenthe between 3350-2700 BC are the most ancient monuments of the Netherlands. They consist of a long assemblage of rocks capped with boulders which served as burial chambers for the Funnel Beaker population. Despite their robust look, dolmens are vulnerable. For example, one of the caprocks of dolmen D14...master thesis 2022

Colombo, Carla (author), Savalle, Nathanaël (author), Mehrotra, A.A. (author), Funari, Marco Francesco (author), Lourenço, Paulo B. (author)The present work aims to expand the knowledge of the behaviour of masonry corners, which are capital to obtain an integral seismic response in masonry buildings. In particular, the influence of the seismic load orientation (from π/4 to π/2) is investigated experimentally, numerically and analytically. Both units and interfaces have been...journal article 2022

Aleo, A. (author)Use-wear traces are considered to be material specific. The use of an appropriate reference collection is thus fundamental for interpreting tools' function. To test whether a flint reference collection can be used to interpret the function of non-flint tools, I conducted experiments using chert, dolerite, and quartz endscrapers and flakes. I...journal article 2022

Mehrotra, A.A. (author), Liew, Andrew (author), Block, Philippe (author), DeJong, Matthew J. (author)Failure of tall slender masonry structures during earthquakes often involves partial collapse of the structure well-above ground level. Consequently, the elastic response of the structure needs to be considered, which often requires modal analysis using finite element models — the generation of which can be labour-intensive and time-consuming...journal article 2022

Theuws, Emy (author)The lack of insight regarding the stability of many dolmen in the Netherlands is problematic. In 2019, a capstone fell down dolmen D14, greatly damaging this cultural heritage. In order to decide on whether it would be wise to reconstruct this dolmen, it is useful to understand the stability of potential reconstruction scenarios without having...master thesis 2021

(author), Harrison, Richard J. (author), van Leeuwen, Tristan (author), Barnhoorn, A. (author)Our understanding of the past behavior of the geomagnetic field arises from magnetic signals stored in geological materials, e.g., (volcanic) rocks. Bulk rock samples, however, often contain magnetic grains that differ in chemistry, size, and shape; some of them record the Earth's magnetic field well, others are unreliable. The presence of a...journal article 2021

Memar, S. (author), Morales Napoles, O. (author), Hofland, B. (author), Melling, Gregor (author)During the last two decades, increasing vessel size in major German estuaries has led to the significant change of the local loading regime i.e. increased importance of ship-induced waves and currents. As a consequence, the intensity of ship-induced loads has increased considerably, resulting in damage to rock structures such as revetments,...conference paper 2021
