A first application of the space-time LATIN-PGD strategy for solving Newtonian incompressible laminar flows

Simulating flow problems is at the core of many engineering applications but often requires high computational effort, especially when dealing with complex models. This work presents a novel approach for resolving flow problems using the LATIN-PGD…

Physics-based super-resolved simulation of 3D elastic wave propagation adopting scalable diffusion transformer

In this study, we develop a Diffusion Transformer (referred as to DiT1D) for synthesizing realistic earthquake time histories. The DiT1D generates realistic broadband accelerograms (0–30Hz resolution), constrained at low frequency by 3-dimensional …

Investigations of raster layup effect on mechanical and fracture properties of material extruded ABS samples under biaxial loadings

The mechanical properties of 3D printed parts are influenced by the parameters used during the manufacturing process. Among them, the raster orientation plays an important role. In this study, biaxial tensile tests coupled with digital image…

Classical and relativistic balance of configurational forces

This article develops a unified variational framework for configurational (or material) forces in both Classical (3D, non-relativistic) and Relativistic (4D) Continuum Mechanics. Configurational forces describe the evolution of material defects-such…

A combined hardware and software method for the projection center calibration of the diffraction pattern

The precise knowledge of the projection center (PC) coordinates is vital for diffraction techniques, especially for electron backscatter diffraction (EBSD) and transmission Kikuchi diffraction (TKD). Numerous techniques have been proposed for PC…

Divergence-Free Diffusion Models for Incompressible Fluid Flows

Generative diffusion models are extensively used in unsupervised and self-supervised machine learning with the aim to generate new samples from a probability distribution estimated with a set of known samples. They have demonstrated impressive…

Unlocking 2D/3D+T myocardial mechanics from cine MRI: a mechanically regularized space-time finite element correlation framework

Accurate and biomechanically consistent quantification of cardiac motion remains a major challenge in cine MRI analysis. While classical feature tracking and recent deep learning methods have improved frame wise strain estimation, they often lack…

Effective reduced-order approximation for fast and robust MCRE-based parametric identification of nonlinear history-dependent material laws

This article essentially addresses the numerical frugality of model updating procedures using reduced order modelling. Nonlinear material behaviour is tackled in the article with the focus being on elasto(visco)-plasticity and elasto(visco)-plastic…
