Densité en GSBD et approximation d’énergie de rupture fragile
6 février 2018 @ 10:45 – 11:45 – The seminar concerns the approximation à la Ambrosio-Tortorelli of the Griffith energy functional for brittle fracture. While the Griffith energy depends on the n-1 dimensional discontinuity set of any function, the approximating energies are elliptic functionals (depending on a further emph{phase field} variable) so more convenient to minimise by Numerical Analysis techniques. For this reason […]
