Continuum approach to computational multi-scale modeling of fracture
(Trans Tech Publications, 2015-01)
This paper presents a FE2 multi-scale framework for numerical modeling of the structural failure of heterogeneous quasi-brittle materials. The model is assessed by application to cementitious materials. Using the Continuum ...
Model order reduction in computational multiscale fracture mechanics
(Trans Tech Publications, 2016-01)
Nowadays, the model order reduction techniques have become an intensive research field because of the increasing interest in the computational modeling of complex phenomena in multiphysic problems, and its consequent ...
Miscible transfer of solute in different model fractures: From random to multiscale wall roughnessTransport miscible de solutés dans différentes fractures modèles : influence de la rugosité aléatoire ou multiéchelles
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2010-07)
Miscible tracer dispersion measurements in transparent model fractures with different types of wall roughness are reported. The nature (Fickian or not) of dispersion is determined by studying variations of the mixing front ...
Computational multiscale modeling of fracture problems and its model order reduction
(International Center for Numerical Methods in Engineering, 2017)
This work focuses on the numerical modeling of fracture and its propagationin heterogeneous materials by means of hierarchical multiscale models basedon the FE2 method, addressing at the same time, the problem of the ...
Multi-scale analysis of the early damage mechanics of ferritized ductile iron
(Springer, 2017-03-18)
A multi-scale analysis of the linear elastic and the early damage stages of ferritic ductile iron is introduced in this work. The methodology combines numerical and experimental analyses in the macro and micro scales. ...
Reduced order modeling strategies for computational multiscale fracture
(Elsevier Science, 2016-10)
The paper proposes some new computational strategies for affordably solving multiscale fracture problems through a FE2 approach. To take into account the mechanical effects induced by fracture at the microstructure level ...

Cohesive surface model for fracture based on a two-scale formulation: computational implementation aspects
(Springer, 2016-10)
The paper describes the computational aspects and numerical implementation of a two-scale cohesive surface methodology developed for analyzing fracture in heterogeneous materials with complex micro-structures. This approach ...
Multiscale modeling of steel fiber reinforced concrete based on the use of coupling finite elements and mesh fragmentation technique
(2018-01-01)
A multiscale model is proposed based on the use of coupling finite elements recently developed by the authors. This feature allows the use of the same strategy to deal with two problems of non-matching meshes addressed in ...
