Botto, L. (author)In liquid-phase exfoliation for the production of 2D nanomaterials fluid forces are used to gently overcome adhesive interlayer forces, leading to single- or few-layer 2D nanomaterials. Predicting accurately the critical fluid shear rate for exfoliation is a crucial challenge. By combining notions of fluid mechanics and fracture mechanics, we...journal article 2019

Krishnasamy, J. (author), Ponnusami, Sathiskumar A. (author), Turteltaub, S.R. (author), van der Zwaag, S. (author)The effect of splat interfaces on the fracture behavior of air plasma-sprayed thermal barrier coatings (APS-TBC) is analyzed using finite element modeling involving cohesive elements. A multiscale approach is adopted in which the explicitly resolved top coat microstructural features are embedded in a larger domain. Within the computational...journal article 2019

Rocha, I.B.C.M. (author), van der Meer, F.P. (author), Taumaturgo Mororo, L.A. (author), Sluys, Lambertus J. (author)Accurate numerical modeling of fracture in solids is a challenging undertaking that often involves the use of computationally demanding modeling frameworks. Model order reduction techniques can be used to alleviate the computational effort associated with these models. However, the traditional offline-online reduction approach is unsuitable...journal article 2019

van Vliet, R. (author)To study interaction between ice and sloping structures, numerical models are required that can predict failure of the ice based on physical ice properties, deformations and structural shape and size. An important element of these models is the set of failure criteria that is applied, as failure limits the loading of the ice on the structure....doctoral thesis 2018

Sherzer, G. (author), Gao, P. (author), Schlangen, E. (author), Ye, G. (author), Gal, E. (author)Modeling the complex behavior of concrete for a specific mixture is a challenging task, as it requires bridging the cement scale and the concrete scale. We describe a multiscale analysis procedure for the modeling of concrete structures, in which material properties at the macro scale are evaluated based on lower scales. Concrete may be viewed...journal article 2017

Zhang, H. (author), Šavija, B. (author), Chaves Figueiredo, S. (author), Lukovic, M. (author), Schlangen, E. (author)This work aims to provide a method for numerically and experimentally investigating the fracture mechanism of cement paste at the microscale. For this purpose, a new procedure was proposed to prepare micro cement paste cubes (100 × 100 × 100 µm3) and beams with a square cross section of 400 × 400 µm2. By loading the cubes to failure with a...journal article 2016
