• Informed boundary condition and constitutive parameter calibration via Identifiability Classes · 2027

  Résumé de la publication : This paper presents an enhanced method for sequential identification of boundary condition and constitutive parameters, incorporating advanced measurement uncertainty-based sensitivity analysis through Identifiability Classes. The approach is further optimized by implementing an a priori selection of regularization weight, significantly accelerating the identification…

• Effect of weld imperfections on the fatigue resistance of butt-welded connections · 2027

  Résumé de la publication : Existing standards and recommendations such as prEN 1993-1-9, IIW recommendations, and EN 13001-3-1, provide reference values for the fatigue resistance of butt-welded connections with reference to ISO 5817 quality levels. Nevertheless, these quality level requirements are primarily based on conservative assumptions and…

• Periodicity and image registration for yarn path extraction in large 3D textiles · 2027

  Résumé de la publication : Accurate identification of yarns in X-ray computed tomography volumes remains a critical and complex step in generating high-fidelity numerical models of woven composites. This work introduces a tracking framework that leverages the intrinsic periodicity of woven architectures to transform a complex, large-scale…

• On Detecting Elastoplastic Shakedown Using Minimal Digital Image Correlation Results and an Elastic Model: Demonstration for AA6061 Auxetic Sheets · 2026

  Résumé de la publication : Background. Shakedown occurs in elastoplastic bodies subject to cyclic loading when limited plastic deformation in the early stages of cycling gives rise to residual stresses that arrest the plastic response. As a result, purely elastic behavior is recovered upon further load cycling.…

• Geometry-agnostic model reduction with GNN-generated reduced POD bases and boosted PGD enrichment for (non)linear structural elastodynamics · 2026

  Résumé de la publication : This contribution proposes a new and significantly enhanced extension of a recently-introduced hybrid Graph Neural Network (GNN)-based reduced-order modeling approach for the numerical solution of time-dependent partial differential equations on non-parametric finite element meshes. Building upon previous proof-of-concept work, this more generalized…
