Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)In fractured geological formations, as a result of the in-situ stress changes, fractures can propagate or slide. This phenomenon can be efficiently modeled by the extended finite element method (XFEM) when there are only a few fractures present. However, geological reservoirs contain many fractures which can also cross and are densely...journal article 2023

Alfaiate, J. (author), Sluys, Lambertus J. (author)In quasi-brittle materials, such as reinforced concrete, localisation of initially diffuse cracking evolving in localised cracking patterns consists of a numerically challenging task. With conventional iterative methods, convergence of the numerical solution scheme to model crack localisation is often difficult to obtain. On the other hand,...journal article 2023

Veeger, M.I.A. (author), Nabbe, Arendje (author), Jonkers, H.M. (author), Ottele, M. (author)Implementing nature in cities has great potential to improve urban liveability by providing ecosystem services, which can help mitigate heat stress, improve air quality, attenuate noise, and reduce rainwater run-off. However, widespread adoption of urban nature and green building typologies is still limited due to their costs, environmental...journal article 2023

Teigiserová, D.A. (author), Reit, Colin A.J. (author), Schraven, D.F.J. (author)The circular economy (CE) has been established as one of the leading strategies to achieve a more sustainable system leading to national and global goals. One of the models coupled with CE is Product-Service Systems (PSS), with service integrated into products to various degree. PSS implementation in the infrastructure sector has been studied...journal article 2023

Alfaiate, J. (author), Sluys, Lambertus J. (author), Costa, A. (author)Corrosion in reinforced concrete is an important feature which can lead to increased deformation and cracking, as well as to premature failure. In the present work, macro-mechanical modelling of corrosion is performed, namely the degradation of bond–slip between concrete and steel. A mixed-mode damage model is adopted, in which the...journal article 2023

Bristogianni, T. (author)Cast glass has great application potential in the architectural realm, yet, despite its possibilities and attractiveness, designers, engineers and developers are, from an early design stage, hesitant to employ it; the limited available and craft-based manufacturing facilities, the questionable quality of the product, the missing engineering data...doctoral thesis 2022

Singla, A. (author), Šavija, B. (author), Sluys, Lambertus J. (author), Romero Rodriguez, C. (author)Lattice models have been used to simulate mass transport to predict durability of cementitious materials. In particular, the use of dual lattice meshes allows for the coupling of fracture and transport processes, which commonly occur at the same time in these materials. Literature has shown good agreement between simulations and experimental...journal article 2022

Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)Altering the state of the stress of the subsurface reservoirs can lead fractures to slip and extend their lengths (i.e., to propagate). This process can even be engineered, in many applications, e.g., enhanced geothermal systems. As such, accurate and efficient simulation of the mechanical deformation of the subsurface geological reservoirs,...conference paper 2022

Zhou, Y. (author), Sluys, Lambertus J. (author), Esposito, R. (author)Accurate assessment of the overall mechanical behavior of masonry, composed of bricks and mortar joints, remains challenging due to its inhomogeneous and orthotropic nature. In this study, the feasibility of various mean-field homogenization schemes for the three-dimensional orthotropic elastic properties of masonry is comprehensively...journal article 2022

Fayezioghani, A. (author), Dekker, R. (author), Sluys, Lambertus J. (author)Structural components in corrosive environments such as pipelines, bridges, aircrafts, and turbines are imposed to stress corrosion. A stress corrosion model for pit growth should a) accurately consider the electrochemistry of the corrosion process, b) properly deal with the moving interface between solid and electrolyte, and c) effectively...journal article 2022

Fayezioghani, A. (author), Dekker, R. (author), Sluys, Lambertus J. (author)Corrosion is a phenomenon observed in structural components in corrosive environments such as pipelines, bridges, aircrafts, turbines, etc. The computational model of corrosion should enjoy two features: a) accurately considering the electrochemistry of corrosion and b) properly dealing with the moving interface between solid and electrolyte....journal article 2022

Fusco, Daniela (author), Addessi, D. (author), Messali, F. (author), Rots, J.G. (author), Pampanin, S. (author)Since the 1980s, calcium silicate element masonry has been commonly used in Dutch buildings, and vertical continuous joints have been usually located at the corner of perpendicular walls. Since the shear failure of these joints may significantly reduce the seismic performance of the flanged wall and therefore of the entire building, the...journal article 2022

li Piani, T. (author), Weerheijm, J. (author), Sluys, Lambertus J. (author)Adobe is a traditional masonry made of sundried earthen bricks and mud mortar. Despite a millennial history of buildings of architectural value, adobe still connotes a so called ‘not engineered’ construction type. Namely, the material and structural properties of adobe are still not entirely addressed, resulting in an equally uncertain...journal article 2022

Understanding the hydraulics of flow with planted floodplains is of great significance for determining the velocity distribution profile and supporting the fluvial processes management. However, the...journal article 2021

Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)Deformable fractured porous media appear in many geoscience applications. While the extended finite element method (XFEM) has been successfully developed within the computational mechanics community for accurate modeling of deformation, its application in geoscientific applications is not straightforward. This is mainly due to the fact that...journal article 2021

(author)This study presents calibration and validation of a cohesive extended finite element model for fatigue crack propagation in ductile materials. The approach relies on a separation between plasticity around the crack tip and fatigue crack growth at the crack tip such that the influence of plasticity on fatigue driving forces is predicted. This...journal article 2021
