Observation of Bulk Plasticity in a Polycrystalline Titanium Alloy by Diffraction Contrast Tomography and Topotomography
J. C. Stinville, W. Ludwig, P. G. Callahan +4
The mechanical properties of polycrystalline metals are governed by the interaction of defects that are generated by deformation within the 3D microstructure. In materials that def…
Concurrent multiscale analysis without meshing: Microscale representation with CutFEM and micro/macro model blending
Ehsan Mikaeili, Susanne Claus, Pierre Kerfriden
In this paper, we develop a novel unfitted multiscale framework that combines two separate scales represented by only one single computational mesh. Our framework relies on a mixed…
Uncertainty quantification in a mechanical submodel driven by a Wasserstein-GAN
Hamza Boukraichi, Nissrine Akkari, Fabien Casenave +1
The analysis of parametric and non-parametric uncertainties of very large dynamical systems requires the construction of a stochastic model of said system. Linear approaches relyin…
Multiscale analysis of crystal defect formation in rapid solidification of pure aluminium and aluminium-copper alloys
Tatu Pinomaa, Matti Lindroos, Paul Jreidini +6
Rapid solidification leads to unique microstructural features, where a less studied topic is the formation of various crystalline defects, including high dislocation densities, as…
Uncertainty quantification for industrial design using dictionaries of reduced order models
Thomas Daniel, Fabien Casenave, Nissrine Akkari +2
We consider the dictionary-based ROM-net (Reduced Order Model) framework [T. Daniel, F. Casenave, N. Akkari, D. Ryckelynck, Model order reduction assisted by deep neural networks (…
Observation of long turn-on delay in pulsed quantum cascade lasers
E. D. Cherotchenko, V. V. Dudelev, D. A. Mikhailov +16
We present an experimental study of the turn-on delay in pulsed mid-infrared quantum cascade lasers. We report the unexpectedly long delay time depending on the pumping current, wh…
