Multiple-Input Fourier Neural Operator (MIFNO) for source-dependent 3D elastodynamics

Numerical simulations are essential tools to evaluate the solution of the wave equation in complex settings, such as three-dimensional (3D) domains with heterogeneous properties. However, their application is limited by high computational costs and…

High-vacuum laser treatments enhance strength, ductility and fatigue limit of additively manufactured stainless steel

Post-process laser scanning under high vacuum is proposed as a non-isothermal heat treatment to simultaneously refine the intragranular microstructure near the surface and reduce surface roughness, while also preventing oxidation, in order to…

A novel DDDAS architecture combining advanced sensing and simulation technologies for effective real-time structural health monitoring

A still open question is how to design smart and autonomous mechanical structures able to perform online monitoring of their integrity and take anticipated actions during service before downtime of failure occur. To address this question, we present…

Digital image correlation analyses of masonry infilled frame: Uncertainty-based mesh refinement and damage quantification

Masonry walls are subjected to cyclic lateral loads to study damage caused by earthquakes. Imaging techniques are useful to quantify crack networks in such tests, where preferential locations for their initiation are not present. However, detecting…

Characterization of a sedimentary basin using geophysical measurements: example of the Mugello basin, Italy

The ambition of the French ACROSS (ArChaeology, inventory of RecOnstruction, Seismology and Structural engineering, across-project.github.io) project is to study past earthquakes through their impact on historical buildings. Based on an…

A multi-disciplinary approach to the study of cultural heritage towers

This work develops tools and approaches to analyze the dynamic behavior of old slender masonry structures. Two scales of analysis are considered to study these structures: global scale (for a set of structures) and local scale (for a specific tower)…

Deep-learning-based surrogate model of laser-induced elastic wave propagation in metallic microstructures with elongated grains

The displacement field of laser-induced elastic waves propagating at the surface contains information about the physical properties of the medium at shallow depths (Rayleigh wavelength). This information can be used to characterize the…
