On the proper characterization of tooling motions and initial conditions in powder die compaction modeling
(2011-08)
Article
Open AccessThe present paper is concerned with the finite element modeling of Powder Metallurgy (P/M) cold die compaction process. Rather than on material constitutive theories or on numerical algorithmic issues, attention is confined ... -
Numerical modeling of crack formation in powder forming processes
(2011-01)
Article
Open AccessThis paper presents a constitutive model describing the mechanical behavior of metal powders during (uniaxial) cold die compaction processes, placing special emphasis on the modeling of cracks formed during the ejection ... -
Strain localization, strong discontinuities and material fracture: matches and mismatches
(2012-10)
Article
Open AccessThe work focuses on the connections of strain localization modeling of material failure and discrete fracture mechanics. It is an attempt to give an answer to the old question of whether the finite element solutions of ... -
On the contact domain method: a comparison of penalty and Lagrange multiplier implementations
(2012-01)
Article
Open AccessThis work focuses on the assessment of the relative performance of the so-called contact domain method, using either the Lagrange multiplier or the penalty strategies. The mathematical formulation of the contact domain ... -
A macroscopic damage-plastic constitutive law for modeling quasi-brittle fracture and ductile behavior of concrete
(2012-04)
Article
Open AccessA new phenomenological macroscopic constitutive model for the numerical simulation of quasi-brittle fracture and ductile concrete behavior, under general triaxial stress conditions, is presented. The model is particularly ... -
Finite element modelling of ejection cracks in powder metallurgy die compaction processes: case study
(2012)
Article
Open AccessTo date, the modelling of crack formation during the ejection stage in powder metallurgy die compaction processes has fallen outside the scope of conventional finite element studies on this process. In this paper, we attempt ... -
A finite strain, finite band method for modeling ductile fracture
(2012-01)
Article
Open AccessWe present a finite deformation generalization of the finite thickness embedded discontinuity formulation presented in our previous paper [A.E. Huespe, A. Needleman, J. Oliver, P.J. Sánchez, A finite thickness band method ... -
Structural size effect: experimental, theoretical and accurate computational assessment
(Elsevier, 2020-06)
Article
Restricted access - publisher's policyIn this paper, experimental evidence, theoretical predictions and the finite element modelling of the structural size effect in cracking problems of quasi-brittle materials are discussed and assessed against each other. ... -
Probabilidad y geotecnia (segunda parte)
(1976)
Article
Open AccessSe presenta a continuación la segunda y última parte del artículo cuya publicación se inició en el número anterior. En ella se abordan los números probabilistas a nivel macroscópico, aproximación discontinua, con aplicación ... -
Probabilidad y geotecnia (primera parte)
(1976)
Article
Open AccessEn la solución de los problemas geotécnicos pueden seguirse vías deterministas o probabilistas, según la consideración que se haga o no de los criterios de probabilidad. En el artículo, que consta de dos partes, se pasa ... -
Mecanismo de contaminación salina del acuífero profundo del borde septentrional del delta del río Llobregat (Puerto Franco-Barcelona )
(1978-10)
Article
Open AccessEl presente artículo define el posible mecanismo de contaminación salina del acuífero profundo del delta del río Llobregat en su parte septentrional (Puerto Franco-Barcelona) de acuerdo con los datos obtenidos últimamente. -
