Simulation-guided PGD-Stereocorrelation for hybrid testing

Hybrid testing aims to evaluate the dynamics of a large scale structure from which an isolated part is experimentally tested, while the rest is simulated in the control loop for imposing earthquake-induced motions at boundaries. One of these tests,…

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…

Piezoelectric polymer generators: The large bending regime

There is an important difference between piezoelectric polymer films and solid crystals for the application of piezoelectric generators. In the case of polymers, the optimal piezoelectric response imposes a large bending regime. Starting from the…
