Materials and structures in mechanics

A real-time variational data assimilation method based on complexity reduction and on-the-fly data-driven empirical enrichment

State estimation is a specific data assimilation task in which the quantity of interest is the state of the physical system over a domain of interest. For that purpose, we rely on observations on the system, given by sensors at different sampling…

Materials and structures in mechanics

A real-time variational data assimilation method with model bias identification and correction

Real-time monitoring on a physical system by means of a model-based digital twin may be difficult if occurring phenomena are multiphysics and multiscale. A main difficulty comes from the numerical complexity which is associated to an expensive…

Calibration of Crystal Orientation and Pattern Center of EBSD using Integrated Digital Image Correlation

The accuracy of electron backscatter diffraction indexation has long been limited by pattern center determination, and numerous hardware and software methods have been proposed to improve the calibration. Here, an Integrated Digital Image…

Seamless Simulations of Earthquake Disasters and Economy at 1:1 scale Utilizing Big-data

We present a novel approach for utilizing big data to estimate economic impacts of disasters by performing end-to-end simulations of disasters and economy at 1:1 scale. In order to realize such fine-grained economic simulations, we developed a high…

Anatomy of strike-slip fault tsunami genesis

Significance Our work has uncovered unexpected potential for strike-slip faults to generate devastating tsunamis, without necessarily triggering coseismic underwater landslides or slumps with their associated wave generation. This is a previously…

A new mechanism-based temperature-dependent viscoelastic model for unidirectional polymer matrix composites based on Cartan decomposition

A new three-dimensional temperature-dependent viscoelastic constitutive model for unidirectional fiber reinforced, polymer composite materials subjected to small strains is developed in this work. The key point is to introduce the viscoelastic…
