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 ...
A dissipative approach to the stability of multi-order fractional systems
(Oxford University Press, 2020)
Real-order generalization of dissipativeness and passivity concepts are presented in this paper. They are characterized as properties of a system; that is, they are independent of the system's internal representation and ...
Homogenization of the Navier-Stokes equations by means of the Multi-scale Virtual Power Principle
(Elsevier Science Sa, 2017-03)
This work addresses the multi-scale modeling of fluid flow in highly complex media based on the concept of Representative Volume Element (RVE). The Method of Multi-scale Virtual Power developed by the authors is employed ...
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. ...
A multi-core computing approach for large-scale multi-label classification
(IOS Press, 2017-03)
Large scale multi-label learning, i.e. the problem of determining the associated set of labels for an instance, is gaining relevance in recent years due to the emergence of several real-world applications. Most notably, ...
Multi-scale surface patterning – an approach to control friction and lubricant migration in lubricated systems
(Emerald Group Publishing Ltd., 2019)
Purpose: The paper aims to investigate the possibilities to control friction in lubricated systems by surface patterning, making use of a multi-scale approach. Surface patterns inside the tribological contact zone tend to ...
A FE 2 multi-scale implementation for modeling composite materials on distributed architectures
(Techno-Press, 2019-04)
This work investigates the accuracy and performance of a FE2 multi-scale implementation used to predict the behavior of composite materials. The equations are formulated assuming the small deformations solid mechanics ...
Confrontación de escalas temporales en Arqueología histórica
(Universidad Nacional de Rosario. Facultad de Humanidades y Artes. Centro de Estudios de Arqueología Histórica, 2014)
During the archaeological analysis and the interpretation some different temporal scales are used: from microscopic observations of the artifact until interregional and interethnic comparisons. Faced with the routine use ...
Effective properties of nodular cast-iron: A multi-scale computational approach
(Elsevier Science, 2014-02)
A numerical approach based on a computational constitutive multi-scale model is used in this work to predict the effective Young’s modulus and Poisson’s ratio of a pearlitic nodular cast iron. The Representative Volume ...
