An Open Database to Evaluate the Fundamental Frequency of Historical Masonry Towers through Empirical and Physics-Based Formulations

The fundamental frequency plays a primary role in the dynamic assessment of Cultural Heritage towers. Local and global features may impact its value: geometric, material features, interaction with the soil and adjacent buildings, aging, the…

Numerical framework for data-driven model-based monitoring of dynamical systems - Application to earthquake engineering

The EMSI laboratory (CEA Saclay) is equipped with shaking tables that allow to assess the seismic performance of civil engineering constructions. The control laws of the hydraulic actuators that drive them do not directly integrate the health…

Prediction of the nonlinear transversal compression behavior of high performance fibers using machine learning

Experimental determination of the nonlinear mechanical behavior of high performance fibers is still a big challenge due to tiny size of these materials at the micrometer level. This study proposes a prediction of the nonlinear behavior of these…

Multi-scale Modelling of the Ballistic Impact of One Single Kevlar Yarn

In this work, a multi-scale model of one single crimped Kevlar yarn under ballistic impact is developed. To gain the computation time, the yarn is divided into two parts. While the impact zone is simulated on the microscopic scale, the other zone is…

Influence de défauts de fabrication sur le comportement endommageable de tubes CVI-SiC/SiC élaborés par enroulement filamentaire sous sollicitation de traction cyclée

SiC/SiC composites are attractive candidates for fuel cladding applications in pressurized light-water reactors. In this study, fuel cladding tubes were manufactured by filament winding, and the matrix was deposited by CVI process (Chemical Vapour…

Highlighting the Impact of the Construction History of a Cultural Heritage Building Through a Vibration-Based Finite Element Model Updated by Particle Swarm Algorithm

Numerical models play a primary role in Cultural Heritage preservation. Nevertheless, the design of a realistic model remains challenging due not only to the complex behavior of masonry but also to the asynchronous building phases, the damage…

High speed stereo-vision study of laminated glass fragmentation upon impact

The dierent stages of an impact on laminated glass are dicult to observe and quantify but are essential for numerical model validation. To assess the performance of this composite to low-velocity (∼10 m/s) high-mass impacts, dynamical impact tests,…
