Residual correction for POD-Galerkin reduced order models via conditional VAEs: Application to the bias-aware solution of forward and inverse problems

POD-Galerkin reduced order models (PGROMs) significantly accelerate the solution of parameterized partial differential equations (PDEs) but can suffer from accuracy limitations across the parameter space. We propose a hybrid framework that augments…

Noise-bias compensation for the unsupervised learning of constitutive laws

The Efficient Unsupervised Constitutive Law Identification and Discovery (EUCLID) framework allows the non-supervised learning of constitutive laws from full-field displacement data and global reaction forces. Nonetheless, its accuracy is adversely…

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…

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…
