Non-Intrusive Coupling of Neural Network-Based Local Model and Explicit Dynamics Scheme: Application to Spot-Welded Plates under Impact

Solving large structural problems with multiple complex localized behaviors poses significant challenges, primarily due to the requirement of a fine mesh to capture local features and the need for a fine time step to satisfy the CFL condition. To…

Solid mechanics

A data-driven approach using Neural Networks for real-time modeling and simulation of structures with many welded points under impact

Large structural problems with complex localized behaviour are extremely difficult to solve. In the past, intrusive and non-intrusive domain decomposition methods (DDMs) have been developed to address this challenge. To further reduce computational…

Development of a simplified model for the transient dynamic analysis of bolted assemblies

Bolted joints are essential components of assemblies as they are usually the site of significant stresses as well as numerous non-linearities. In addition, they are widely encountered in mechanical engineering, especially in aeronautics (e.g., 3,000…

Wireframe Modeling of Overhead Conductors for Life Time Prediction

Predicting the lifespan of overhead power conductors is one of the major challenges of the energy sector as it would allow the implementation of more relevant asset management strategies. In this context, wind loadings are particularly studied…

Development of a Homogenized Thermomechanical Model for the Optimized Design of Fiber Optic Gyroscopes

Fiber Optic Gyroscopes (FOG) are high-precision measurement devices that measure the rotation rate of a fiber optic coil along its axis thanks to the Sagnac effect. Two counterpropagative waves are sent into an optical fiber coil. The…

Stability of the critical distance method for fretting cracking prediction: influence of microstructure and crack nucleation size

To provide lifetime predictions of metal pieces under fretting-fatigue loading, the crack initiation process has to be understood. However, there is no consensus in the literature over the crack nucleation length. The objective of this study is to…

Multimaterial Filtering applied to Topology Optimization of a Permanent Magnet Synchronous Machine

This paper proposes a generalized multi-material filtering formalism in density-based topology optimization. This work’s novelty is the consideration of the periodic and anti-periodic boundary conditions commonly used to simulate electrical machines…
