Fast estimation of the influence of a tensile plastic strain on the magnetic behavior of electrical steels

Residual stress, hardening, and defects introduced during the cutting process lead to a global degradation of the magnetic properties of electrical steels. Modeling these phenomena requires preliminary measurements beginning by characterizing the…

Microstructure and micromechanical properties of microcellular AlSi10Mg produced via LPBF

Laser Powder Bed Fusion (LPBF) is an advanced additive manufacturing (AM) process that allows for the fabrication of complex-shaped metallic materials — colloquially referred to as architected materials. While it offers high design flexibility, LPBF…

Efficient Inverse Modeling of Flow Problems Using the Non-Intrusive Reduced Basis Two-Grid Method

Ensemble-based inverse modeling that employs high-fidelity (HF) models can be computationally prohibitive due to the need for repeated model simulation across a wide range of uncertain parameters. To address this limitation, we introduce a…

One or two meshes for Lip-field and Phase-field damage formulations? Comparison and performance assessment of standard and alternative FE solvers

Continuum models developed within the framework of damage mechanics are commonly used to represent the behavior of brittle and quasi-brittle materials. However, as the material softens, the formulation become ill-posedness and loses objectivity. To…

Towards effective robust design of hierarchical industrial models

Complex industrial models are of hierarchical nature. To compute those models non-intrusive local/global coupling using legacy codes have been introduced in the past. The proposal aims ay developing an efficient non-intrusive coupled global-local…

Fluorescence-based detection of apparent crystallization pressure in microfluidic channels

We present a fluorescence-based method for estimating apparent crystallization pressure of halite in polydimethylsiloxane (PDMS) microfluidic channels. A fluorescent dye is uniformly embedded within the PDMS matrix, converting stress-induced…

Data-driven adaptive mesh refinement for enhanced FE-DIC in the presence of cracks

Global Digital Image Correlation (DIC) allows for accurate characterization of fracture phenomena through robust kinematic registrations. The displacement discontinuity can be trustfully highlighted using a finite element mesh, whereby the…
