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…

Score-Based Diffusion Models with Autocorrelation Regularization for Fluid Flow Prediction

The simulation of turbulent flows is an essential field of study with widespread applications. While traditional solvers struggle to provide rapid estimations of solutions due to the intrinsic chaotic nature of turbulence, recent breakthroughs in…

Recueil de communications école d'hiver 2025 GDR ARCHI-META - DN METACMED

The last 20 years have seen a remarkable growth in scientific interest in (elastic and mechanical) metamaterials. One of the reasons for this is the great potential that this subject area has in itself as a “link between different disciplines”,…

Comparative Hygrothermal Performance of a Mortar Wall with Micronized Miscanthus Fibers versus a Reference Wall: Experimental and Numerical Analysis

Miscanthus fibres are regarded as a sustainable, eco-friendly material with high hygroscopicity and low thermal conductivity. Although promising at the material scale, further wall-scale evaluations are needed. This study investigates the…

Three-dimensional beam-to-beam frictional contact with small-sliding and finite rotations

Abstract Stranded cables, composed of multiple twisted wires, exhibit high tensile strength and flexibility, making them essential in numerous industrial applications, such as mooring lines for offshore structures, overhead conductors, and cable…

Physical-chemical characterization of a crystallinity gradient in a carbon black-filled PEEK laminate manufactured by laser-assisted tape placement

Laser-assisted tape placement (LATP) of thermoplastic composites (TPC) enables the rapid production of laminates. However, during layup, higher cooling rates are expected on the bonded interphases between two plies (in the vicinity of the interply),…
