Séminaire – Cédric Bellis ‘Variational principles for computational homogenization and strategies for improving the performances of Fourier spectral methods’
Centrale Nantes - Amphi C117 1 rue de la Noë, NantesRésumé Variational principles for computational homogenization and strategies for improving the performances of Fourier spectral methods. The homogenization of periodic elastic composites can be addressed through the reformulation of the local equations of the mechanical problem into energetic variational principle. We review such principles and describe a computational, FFT-based, approach…
