Augmented DIC and FE Analyses: A Two-Field Approach to Damage Localization

The prediction of localized phenomena is still challenging. In particular, running an entirely consistent simulation with experimental observations is delicate. It is proposed that FE simulations on fine meshes be augmented with experimentally…

Cinématiques des milieux généralisés et repères mobiles

This work presents a unified geometrical framework for modeling generalised continua in finite strains : in any dimension (rods, shells, 3D media), in any micromorphic theory of order one (micromorphic, Cosserat, micro-dilatation, etc) and in any…

A new Neural Network-based methodology for multi-level topology optimisation in structural problems

The optimisation of high-resolution trabecular structures is crucial for various industrial applications due to their resilience to unexpected loads. Current topology optimisation (TO) approaches face challenges like high computational costs and…

A step toward flow simulation through cracks in beam-particle models

Crack characterization in reinforced concrete structures, such as the containment walls of 1300 MWe nuclear power plants, is critical for accurately estimating air leakage. Traditional modeling strategies, such as Poiseuille's law applied to a…

Magnetoelastic behavior of DP steel in biaxial mechanical loading condition - Equivalent stress for magnetostriction

Online non-destructive magnetic monitoring is used to control the quality of steels subjected to multiaxial stresses. Due to magneto-elastic effects, a correction of non-destructive signal is necessary requiring the use of predictive magneto-elastic…

Accelerating cell topology optimisation by leveraging similarity in the parametric input space

The design of high-resolution topology-optimised (TO) structures is important for many industrial and medical applications because of their better mechanical performance under different load conditions. Traditional density-based TO methods, like the…

Physics-Based Super-Resolved Simulation of 3D Elastic Wave Propagation Adopting Scalable Diffusion Transformer

In this study, we develop a Diffusion Transformer (referred as to DiT1D) for synthesizing realistic earthquake time histories. The DiT1D generates realisticbroadband accelerograms (0-30 Hz resolution), constrained at low frequency by 3-dimensional …

Rescaling and mesoshear deformations of lattice metamaterials

Experimental results are presented for a lattice metamaterial with a complex mesostructure composed of parallel fibers aligned at different levels. The experimental evidence suggests that the fibers, in addition to their own deformations, such as…
