On the identification of rigid body boundary conditions from full-field measurements

This study presents a method to identify Dirichlet boundary conditions (BCs) and constitutive parameters from heterogeneous experimental data, solving a multi-objective optimization problem. The BCs are parameterized as remote rigid body motions…

A space-time LATIN-PGD strategy for solving Newtonian compressible 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…

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…
