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…

Oyster shell concrete durability in marine environment

Each year, 6.6 million tons of oysters are produced worldwide, representing an important amount of waste that can be valorized in cementitious materials. In particular, oyster shell co-products can replace coarse aggregates up to a 50% volume…

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…
