Mechanics

Simplified model for the transient dynamic analysis of bolted assemblies

Bolted joints are crucial in assembly structures, particularly due to the high stresses and complex non-linear behaviours they experience. These joints are common in mechanical engineering applications, notably in aeronautics, where a single…

Modelling the impact of linear infrastructure on species dispersal in a changing climate: a scalable surrogate approach

As climate change accelerates, many species must shift their ranges to survive. Yet humanmade linear infrastructures-such as roads, railways, and power lines-fragment habitats and create major barriers to movement. Understanding and mitigating these…

Virtual Design of Masonry Triplet Shear Tests using Digital Image Correlation

Numerous studies highlight the diverse opportunities offered by multi-view image correlation techniques. For example, in masonry structures, these techniques enable the propagation of cracks to be quantified in joints and blocks. However, many…

Data-driven Fluid Flow Prediction Using Conditional Score-based Diffusion Models

Advances in computational power have made turbulent field simulations central to many disciplines, yet traditional solvers struggle to deliver fast flow estimations due to the inherent chaotic nature of the problem. More recently, diffusion models…

Carbon nanotube effects on low-cement mortar performance and eco-efficiency

The construction sector, particularly cement production, accounts for 8-10 % of global CO2 emissions annually, and the industry is under increasing pressure to adopt sustainable practices, with carbon nanotubes (CNTs) emerging as a promising…

Approches local/global non-intrusives et optimisation robuste

Les approches de submodeling sont très prisées par les industriels car elles permettent de réanalyser à faible coût, au sein de logiciels commerciaux, des zones locales jugées critiques en raffinant les maillages et la description de la géométrie ou…

Nonlinear Sciences

Extension of quasi-static damage meso-modelling of composite laminates to dynamic failure and erosion

Impact tests on structures are destructive, costly and difficult to analyze. This is particularly true for composite structures, whose properties and failure mechanisms are highly dependent on the chosen stacking architecture. As a result, virtual…

Accelerating nonlinear finite element analysis via residual-aware neural network constitutive models

Nonlinear finite element analysis (FEA) relies heavily on iterative methods such as the Newton-Raphson algorithm, with computational cost primarily driven by the repeated solution of large linear systems (global stage) and the evaluation of…
