Investigation of the influence of design and material parameters in the progressive collapse analysis of RC structures
B. Santafé Iribarren,B. Santafé Iribarren,Peter Berke,Ph. Bouillard,John Vantomme,Thierry Massart +5 more
TL;DR: In this article, one-dimensional nonlinear constitutive laws are used to model the material response of reinforced concrete and steel in a layered beam approach, in order to derive physically motivated relationships between generalised stresses and strains at the sectional level.

Multiscale computational modelling of closed cell metallic foams with detailed microstructural morphological control
A. Ghazi,A. Ghazi,Peter Berke,K. Ehab Moustafa Kamel,Bernard Sonon,Carlos Tiago,Thierry Massart +6 more
TL;DR: In this paper, the authors address the multiscale computational modeling of closed cell metallic foams by means of an integrated Representative Volume Element (RVE) generation and computation strategy, where microstructural geometry is computationally generated by controlling relevant fine scale features such as the distribution of cell sizes, the spatial organization of cell size and that of cell wall thicknesses and curvatures.

Computed tomography based modelling of the behaviour of closed cell metallic foams using a shell approximation
TL;DR: In this article, an imaged-based shell modeling strategy for closed cell metallic foams exploiting X-ray Computed Tomography scans, with its illustration on ALCORAS® foams, is presented.

Computational design of bistable deployable scissor structures: trends and challenges
TL;DR: The trends and challenges of using computational tools in the structural analysis and design process of deployable bistable structures are discussed and a deeper understanding of the complex transformation behaviour of these structures is explored.
Study of the rate-dependent behavior of pure nickel in conical nanoindentation through numerical simulation coupled to experiments
TL;DR: In this paper, the results of numerical simulations coupled to nanoindentation experiments conducted at various indentation depths and at different load rates on pure nickel are presented, and a good agreement between the experimental and the numerical results can be obtained for both the load levels and the creep indentation phase (displacement-time curves in the holding period) when taking into account a simple model with rate-dependent material behavior, and using a material parameter set that is in the acceptable domain for metals.
