One of the main drawbacks of such approaches is the lack of a rigorous frame based on the laws of physics. Here we propose a new class of data driven, physics based, neural networks for constitutive modeling of strain rate independent processes ...
[2]		Benchmarking virtual permeability predictions of real fibrous microstructure, David May, Elena Syerko, Tim Schmidt, Christophe Binetruy, Luisa Rocha da Silva, Stepan Lomov, Suresh Advani, 36th Technical Conference of the American Society for Composites 2021 Composites Ingenuity Taking on Challenges in Environment Energy Economy ASC 2021, Vol. 3, pp. 2123-2132, ISBN:[9781713837596] (2021)	For fast and complete impregnation in Liquid Composite Molding, knowledge about the permeability of the fibrous reinforcement is required. While development of experimental methods continues, a parallel benchmark effort to numerically characterize permeability is being pursued. The approach was to send out the images of a real fibrous microstructure to a number of participants, in order for them t...

[4]		Chloride ions penetration of alkali-activated fly ash mortars with ground granulated blast furnace slag, Patrycja Duzy, Mateusz Sitarz, Marcin Adamczyk, Marta Choinska, Izabela Hager, Fib Symposium, Vol. 2021-June, pp. 284-293, ISBN:[9782940643080] (2021)	Due to the need to reduce the CO2 emissions of natural binders researchers are considering the use of alkali activated materials (AAMs) as an alternative to traditional cementitious binders. The properties of AAMs (e.g. low shrinkage and fire resistance) can be more advantageous to those presented by cementitious binders, and thus they can replace Portland cement binders in some applica...
[5]		EFFECT OF MINERAL ADDITIONS ON THE SELF-HEALING ABILITY OF CEMENTITIOUS MATERIALS, Carol Namnoum, Benoit Hilloulin, Maxime Robira, Frederic Grondin, Ahmed Loukili, American Concrete Institute ACI Special Publication, Vol. SP-349, pp. 1-14, ISBN:[9781641951395] (2021)	The production of cement by calcination of limestone releases large amounts of carbon dioxide. Development of concrete quality lead to optimize the sustainability and maintenance phases of concrete structures, so, using supplementary cementitious materials (SCM) is one of the methods adapted to reduce the environmental impact of cement production. In addition, self healing of concrete appears as a...

Several mechanical models based on damage theory have been developed to represent the behavior of reinforced concrete structures subjected to cyclic loading. The use of these models requires knowledge about the model parameters which could be determined from experimental tests. However, ther...

[10]		Finite element-fidelity parametrization of kriging metamodels for structutal reliability assessement, Ludovic Mell, Valentine Rey, Franck Schoefs, Proceedings of the 31st European Safety and Reliability Conference Esrel 2021, pp. 2777, ISBN:[9789811820168], Research Publishing Services (2021), doi:10.3850/978-981-18-2016-8_696-cd	It is critical to obtain a precise estimation of the probability of failure when doing the reliability analysis of a given structure. The Monte carlo estimator is a non intrusive and unbiased estimator than can be easily implemented to compute this probability. However, the Monte Carlo estimator requires to simulate the structure for a large number of realizations of input random variables due to ...
[11]		Minimum Localizable Damage for Stochastic Subspace-based Damage Diagnosis, Alexander Mendler, Ambroise Cadoret, Clement Freyssinet, Michael Dohler, Yann Lecieux Laurent Mevel, Carlos Ventura, International Conference on Structural Health Monitoring of Intelligent Infrastructure Transferring Research into Practice Shmii, Vol. 2021-June, pp. 1553-1560 (2021)	This article describes an approach to evaluate the minimum localizable damage for stochastic subspace based damage diagnosis. Localizability is defined as the sensitivity to small and local damages (detectability), the ability to narrow down the exact damage location (localization resolution), and the test response of undamaged parameters (false localization alarms). For the analysis, damage is de...
[12]		Effect of the simplified superstructure and soil-structure interaction models on the natural frequencies of an offshore wind turbine, Philip Alkhoury, Abdul Hamid Soubra, Valentine Rey, Mourad Ait-Ahmed, Proceedings of the International Conference on Offshore Mechanics and Arctic Engineering OMAE, Vol. 9, ISBN:[9780791885192], American Society of Mechanical Engineers (2021), doi:10.1115/OMAE2021-62472	Monopile supported offshore wind turbines (OWTs) are dynamically sensitive structures, in which their design is principally based on a dimensioning criterion related to its fundamental frequencies. Therefore, an accurate estimation of the natural frequency is essential to assess the working lifetime of the OWT. For the calculation of the OWT natural frequency, several studies exist but few of them...
[13]		Vibration control of an offshore wind turbine, Philip Alkhoury, Mourad Ait-Ahmed, Abdul Hamid Soubra, Valentine Rey, Proceedings of the International Conference on Offshore Mechanics and Arctic Engineering OMAE, Vol. 9, ISBN:[9780791885192], American Society of Mechanical Engineers (2021), doi:10.1115/OMAE2021-62210	In order to reduce their cost, offshore wind turbines (OWTs) must have a powerful generator and a minimum overall weight. This has the consequence of making the OWT structure sensitive to dynamic excitations even at low frequencies. Indeed, modern multi megawatt OWTs are composed of slender flexible and lightly damped components. The excessive vibrations of the OWT structure can impact the wind en...
[14]		Effect of the installation process on the pullout capacity of helical anchors, Abdul Kader El Haj, Abdul Hamid Soubra, Proceedings of the International Conference on Offshore Mechanics and Arctic Engineering OMAE, Vol. 4, ISBN:[9780791885147], American Society of Mechanical Engineers (2021), doi:10.1115/OMAE2021-62211	In this paper, an advanced numerical method called Coupled Eulerian Lagrangian (CEL) method is used for the prediction of the behavior of helical anchors in sandy soil under ultimate limit state ULS including the effect of anchor installation process. The CEL analysis allows one to overcome the drawback of the classical finite element FE method in the case of large deformation problems as it takes...
