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…

Model calibration using Identifiability Classes: improved accuracy, robustness and speed

Finite Element Model Updating (FEMU) methods enable for the calibration of model parameters by minimizing the discrepancy between computed and measured data. However, the accuracy and reliability of these methods depend on the identifiability of the…

Breaking better: How defects activate multiple toughening mechanisms in lattice materials

Toughening in heterogeneous lattice materials is commonly attributed to crack path tortuosity, but the relative importance of this and other mechanisms remains unclear because direct experimental evidence is scarce. Here, we introduce isolated, well…

Analytical reliability performance maps for bond wire interfaces in power modules under cyclic thermomechanical loads

Reliability of power modules based on Insulated Gate Bipolar Transistors (IGBTs) is majorly challenged by thermomechanical fatigue, especially at the wirebond-chip interface where lift-off failure mechanisms commonly occur. This paper introduces a…

Corrosion fatigue mechanisms of high-strength steel wires in the presence of various aggressive ions

This work focuses on the corrosion fatigue of high-strength steel wires with diameters of 200 μm. The fatigue load consists of a bending rotation with a stress amplitude between 1300 MPa and 700 MPa. Various solutions at pH 6 containing either…
