Kisoensingh, Arvind (author)Flexural shear failure is a brittle failure mode that can occur in reinforced concrete (RC) beams without stirrups due to the combination of flexural and shear stresses. The failure mode begins with vertical flexural cracks at the bottom of the RC beam central span area due to flexural tensile stresses, followed by diagonal cracks. During...master thesis 2023

Schouwenaars, R. (author), Kestens, L.A.I. (author)While the grain size effect (GSE) is universally observed in polycrystalline metals and alloys, extended dislocation pileups (DPUs) at grain boundaries (GBs) are rarely observed. Although this discrepancy was noticed over 50 years ago, DPUs are still widely accepted as the explanation for the GSE, often expressed as the Hall-Petch (HP)...journal article 2023

Bezemer, Jelle (author)Limiting maximum crack widths is a serviceability limit state, which ensures the durability of reinforced structures. In current practice, maximum crack widths are limited by using additional reinforcement, on top of the amount of reinforcement required for the designed ultimate bearing capacity. Reducing the amount of reinforcing steel used,...master thesis 2022

Yotrisno Lang, Lang (author)In concrete structures, shear failure is one of the failure mechanisms that should be estimated carefully due to its brittle nature. As the technology advances, the capacity of shear in concrete structures can be calculated with the analytical formulation in codes and standards and simulated with NLFEA. The shear capacity is affected by the size...master thesis 2021

Roosen, M.A. (author)In the design process of prestressed bridges and viaducts, the required amount of shear reinforcement is determined with a model that assumes the presence of flexural cracks. In order to keep the design process simple, this model is also prescribed to determine the amount of shear reinforcement for the regions of the structure in which, at the...doctoral thesis 2021

Jamali, S.H. (author)Knowledge on transport properties of fluids is of great interest for process<br/>and product design development in the chemical, food, pharmaceutical, and<br/>biotechnological industry. In the past few decades, molecular simulation has<br/>become a powerful tool to calculate these properties. In this context, Molecular<br/>Dynamics (MD) is...doctoral thesis 2020

Brongers, Brian (author)Recently experiments were conducted at the Technical University of Delft on the size effect of concrete. The size effect is a term used for the relative decrease in shear capacity with an increase in height of the structural member. The beams observed in the experiment failed much sooner than was predicted. These test results have implications...master thesis 2020

Chang, Z. (author), Zhang, Hongzhi (author), Schlangen, E. (author), Šavija, B. (author)The lattice fracture model is a discrete model that can simulate the fracture process of cementitious materials. In this work, the Delft lattice fracture model is reviewed and utilized for fracture analysis. First, a systematic calibration procedure that relies on the combination of two uniaxial tensile tests is proposed to determine the input...journal article 2020

Celebi, A.T. (author), Jamali, S.H. (author), Bardow, André (author), Vlugt, T.J.H. (author), Moultos, O. (author)The number of molecules used in a typical Molecular Dynamics (MD) simulations is orders of magnitude lower than in the thermodynamic limit. It is therefore essential to correct diffusivities computed from Molecular Dynamics simulations for finite-size effects. We present a comprehensive review on finite-size effects of diffusion coefficients...journal article 2020

Zhang, H. (author)Cementitious materials are heterogeneous on mutliple length scales, from nanometres to metres. Consequently, their macroscopic mechanical properties are affected by material structures at all length scales. In pursuit of fundamental understanding the relationship between their multiscale heterogeneous material structure and mechanical properties...doctoral thesis 2019

Kota, Kubair (author)Size effects influence the behavior of composites and have a great effect on their properties such as strength, type of failure, etc. The effects of size of the specimen on the behavior of composite laminates were studied based on numerical analyses of sharp and blunt notched [45/90/-45/0] 4s carbon/epoxy composite laminates. Five different...student report 2019

Andrew Sugianto, ANDREW (author)In the past, many researches on the topic of size effect on concrete structures were mainly focused on the phenomenon of size effect in flexural cracking. The result of those studies can be found today in the concrete structure design specifications of well-known building codes, such as the Eurocode. Nevertheless, the inclusions of the results...master thesis 2019

Irani, N. (author), Nicola, L. (author)During plastic deformation, metal surfaces roughen and this has a deleterious impact on their tribological performance. It is therefore desirable to be able to predict and control the amount of roughening caused by subsurface plasticity. As a first step, we focus on modelling plastic deformation during contact shearing of an FCC metallic...journal article 2019

Dikken, R.J. (author)Sustainability has become an integral part of todays society. A thorough understanding of friction as a major cause of energy dissipation is therefore highly relevant. Friction of rough surfaces in contact is a physical phenomenon that involves multiple length- and time-scales, complicating a full understanding of friction. The fundamental study...doctoral thesis 2017
