From discrete to continuous numerical identification of a geomaterial with an internal length

Abstract

To cite this version:Romain Laniel, Pierre Alart, Stéphane Pagano. From discrete to continuous numerical identification of a geomaterial with an internal length. Computer Methods in Applied Mechanics and Engineering, Elsevier, 2009, 199 (1-4) Investigations by discrete elements highlighted that the characteristic length was dependant on the loading level. These simulations provided access to variables that standard physical experiments cannot provide. Some parameters of a continuous model of TexSol were identified through discrete numerical experiments using a classic procedure. The other parameters were determined by finite element method updating.
