A rheological constitutive model to predict the anisotropic biaxial bending behavior of spiral strands subjected to variable axial force

Spiral strands exhibit dissipative bending behavior when subjected to external axial force. To the best of the authors’ knowledge, only the uniaxial bending behavior of spiral strands subjected to constant axial force has been studied in the…

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…

High-order explicit PDE solvers using trigonometric interpolations of non-periodic functions (with applications to engineering, geophysics, & medicine)

This contribution presents recent developments of a Fourier series-based methodology for the numerical analysis of parabolic and hyperbolic partial differential equations (PDEs) with complex boundary conditions. Such a framework is based on a…

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…
