CONTINUUM APPROACH TO COMPUTATIONAL MULTISCALE MODELING OF PROPAGATING FRACTURE

Jack Oliver, Miguel Andres Caicedo, E. Roubin, Alfredo E. Huespe, Juan Antonio Hernández
2014

A new approach to two-scale modeling of propagating fracture, based on computational homogenization (FE2), is presented. The specific features of the approach are: a) a continuum setting for… (More)

Multiscale formulation for material failure accounting for cohesive cracks at the macro and micro scales

This contribution presents a two-scale formulation devised to simulate failure in materials with heterogeneous micro-structure. The mechanical model accounts for the nucleation of cohesive cracks in… (More)

Continuum approach to the numerical simulation of material failure in concrete

Jack Oliver, Alfredo E. Huespe, Esteban Samaniego, Eduardo Chaves
2004

Some new aspects of the continuum strong discontinuity approach (CSDA) to model material failure in geomaterials are addressed. A new global algorithm, for tracking multiple crack lines/surfaces in… (More)
