Energy-based comparison between the Fourier-Galerkin method and the finite element method
The Fourier-Galerkin method (in short FFTH) has gained popularity in numerical homogenisation because it can treat problems with a huge number of degrees of freedom. Because the method incorporates the fast Fourier transform (FFT) in the linear solver, it ...
ELSEVIER2020Fourier Sampling in Signal Processing and Numerical Linear Algebra
This thesis focuses on developing efficient algorithmic tools for processing large datasets. In many modern data analysis tasks, the sheer volume of available datasets far outstrips our abilities to process them. This scenario commonly arises in tasks incl ...
EPFL2020Characterization of the traces on the boundary of functions in magnetic Sobolev spaces
We characterize the trace of magnetic Sobolev spaces defined in a half-space or in a smooth bounded domain in which the magnetic field Ais differentiable and its exterior derivative corresponding to the magnetic field dAis bounded. In particular, we prove ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2020A Fourier-accelerated volume integral method for elastoplastic contact
Jean-François Molinari, Guillaume Anciaux, Lucas Henri Galilée Frérot
The contact of solids with rough surfaces plays a fundamental role in physical phenomena such as friction, wear, sealing, and thermal transfer. However, its simulation is a challenging problem due to surface asperities covering a wide range of length-scale ...
