Stochastic Modeling of Inhomogeneities in the Aortic Wall and Uncertainty Quantification using a Bayesian Encoder-Decoder Surrogate

no code implementations21 Feb 2022 Sascha Ranftl, Malte Rolf-Pissarczyk, Gloria Wolkerstorfer, Antonio Pepe, Jan Egger, Wolfgang von der Linden, Gerhard A. Holzapfel

Then to assess the uncertainty in the output stress distribution due to this stochastic constitutive model, a convolutional neural network, specifically a Bayesian encoder-decoder, was used as a surrogate model that maps the random input fields to the output stress distribution obtained from the FE analysis.

LaBH$_{8}$: the first high-T$_{c}$ low-pressure superhydride

no code implementations22 Feb 2021 Simone Di Cataldo, Christoph Heil, Wolfgang von der Linden, Lilia Boeri

In the last five years a large number of new high-temperature superconductors have been predicted and experimentally discovered among hydrogen-rich crystals, at pressures which are way too high to meet any practical application.

Bayesian Surrogate Analysis and Uncertainty Propagation

no code implementations11 Jan 2021 Sascha Ranftl, Wolfgang von der Linden

In the process, the contribution of the uncertainties of the surrogate itself to the simulation output uncertainties are usually neglected.
