Strict Discretization Error Bounds on Quantities of Interest in Transient Dynamics

ABSTRACT This work proposes a guaranteed error estimator for linear transient elastodynamics, accounting for both time and space discretization errors. The key lies in the definition of a novel dynamic constitutive relation error formulation, which…

Pipeline for Semantic Segmentation of Large Railway Point Clouds

This paper presents a novel deep-learning pipeline to segment large railway datasets with minimal manual annotation, notoriously time consuming. The pipeline adapts DINOv2 [11] for labeling point clouds, with tailored self-distillation pre-training…

An analytical model for the phase transformation front propagation in superelastic SMA under impact tensile loading

Shape-memory alloys (SMAs) exhibit superelastic behavior due to reversible phase transformations. Under dynamic (impact) loading, phase transformation is experimentally observed to occur along a band whose front propagates throughout the specimen…

Determination of interfacial fracture energy of an environmental barrier coating on ceramic matrix composite substrate

The present work concerns the study of the interface fracture energy between a SiC/SiC Ceramic Matrix Composite and an environmental barrier coating. Four-point flexural tests with no precrack were conducted. These tests enable for the stable…

Brightness and Contrast Corrections for Space-Time Stereocorrelation via Proper Generalized Decomposition

Stereocorrelation (SC) is a flexible, non-contact experimental tool for measuring 3D shape and surface kinematics in complex mechanical tests. The violation of gray level conservation raises the issue of convergence of SC (e.g., when local specular…

Multiple-Input Fourier Neural Operator (MIFNO) for source-dependent 3D elastodynamics

Numerical simulations are essential tools to evaluate the solution of the wave equation in complex settings, such as three-dimensional (3D) domains with heterogeneous properties. However, their application is limited by high computational costs and…

Digital image correlation analyses of masonry infilled frame: Uncertainty-based mesh refinement and damage quantification

Masonry walls are subjected to cyclic lateral loads to study damage caused by earthquakes. Imaging techniques are useful to quantify crack networks in such tests, where preferential locations for their initiation are not present. However, detecting…
