Simulation of frictional contact interactions within a Jacquard harness for 3D interlock weaving

Frictional contact interactions between warp yarns and heddles within a Jacquard harness for 3D interlock weaving are simulated using a finite element code to evaluate efforts in the heddles and to predict the occurrence of blockages that may be…

Deep-learning-based surrogate model of laser-induced elastic wave propagation in metallic microstructures with elongated grains

The displacement field of laser-induced elastic waves propagating at the surface contains information about the physical properties of the medium at shallow depths (Rayleigh wavelength). This information can be used to characterize the…

Generative domain-adapted adversarial auto-encoder model for enhanced ultrasonic imaging applications

In this study, we propose a class-conditioned Generative Adversarial Autoencoder (cGAAE) to improve the realism of simulated ultrasonic imaging techniques, in particular the Multi-modal Total Focusing Method (M-TFM), based on the availability of…

From the PEEK microstructure at welded interfaces to the mechanical properties of thermoplastic composites manufactured by a Laser-Assisted Tape Placement process

The Laser-Assisted Tape Placement (LATP) process of thermoplastic composites enables the rapid production of laminates. However, it generates cooling rates gradients between the surface and the bulk of the plies, probably causing a crystallinity…
