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…
