A BEM model applied to failure analysis of multi-fractured structures
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Due to manufacturing or damage process, brittle materials present a large number of micro-cracks which are randomly distributed. The lifetime of these materials is governed by crack propagation under the applied mechanical ...
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 ...
Continuum approach to the numerical simulation of material failure in concrete
(Wiley, 2004-06)
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 2D/3D cases is proposed. ...
Dual boundary element formulation applied to analysis of multi-fractured domains
(ELSEVIER SCI LTD, 2010)
This paper deals with analysis of multiple random crack propagation in two-dimensional domains using the boundary element method (BEM). BEM is known to be a robust and accurate numerical technique for analysing this type ...
Multiple random crack propagation using a boundary element formulation
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
This paper proposes a boundary element method (BEM) model that is used for the analysis of multiple random crack growth by considering linear elastic fracture mechanics problems and structures subjected to fatigue. The ...
Failure-Oriented Multi-scale Variational Formulation: Micro-structures with nucleation and evolution of softening bands
(Elsevier Science Sa, 2012-12-05)
This contribution presents the theoretical foundations of a Formulation (FOMF) for modeling heterogeneous softening-based materials undergoing strain localization phenomena. The multi-scale model considers two coupled ...
Failure analysis of packing plate in a hyper compressor at a petrochemical plant
(Elsevier, 2008-07)
Cracks in one of the packing plates of a two stage multi-cylinder 250 MPa polymer hyper compressor at a petrochemical plant provoked a gas leak and a plant stop. Fractographic and micrographic analyses and mechanical ...
Elemental Enriched Spaces for the Treatment of Weak and Strong Discontinuous Fields
(Elsevier Science Sa, 2017-01)
This paper presents a finite element that incorporates weak, strong and both weak plus strong discontinuities with linear interpolations of the unknown jumps for the modeling of internal interfaces. The new enriched space ...
