Multiscale Computation of Failure in Granular Materials: A Geomechanics Perspective

The book looks into the multiscale modelling of geomateirals with reference to their mechanical and failure behaviors. Mutliscale approaches are introduced in which the underlying particle micromechanics are described and ultimately homogenized to give way to enrich or structured macroscopic constitutive relationships endowed with small-scale information. The pertinence of such models within continuum approaches such as the finite element method capturing rich failure modes implicating strain localization, fracture and diffuse phenomena is highlighted. The analysis of failure through discrete element modelling on also presented. Finally, the presence of liquid and gas phases within a granular material on covered in relation to saturated and partially saturated media.This book consolidates basic research information such as granular micromechanics, homogenization technics, mutliscale modelling, including finite element and discrete element modelling paradigms all in one place.
