An accurate nonlocal bonded discrete element method for nonlinear analysis of solids: application to concrete fracture tests
(Springer, 2020-05)
Article
Open AccessWe present a numerical procedure for elastic and nonlinear analysis (including fracture situations) of solid materials and structures using the discrete element method. It can be applied to strongly cohesive frictional ... -
A plastic-damage model for concrete
(1989)
Article
Restricted access - publisher's policyIn this paper a constitutive model based on an internal variable-formulation of plasticity theory for the non-linear analysis of concrete is presented. The model uses a new yield criterion which matches experimental data ... -
A consistent characteristic length for smeared cracking models
(John Wiley & sons, 1989-02)
Article
Restricted access - publisher's policyA numerical scheme for crack modelling by means of continuous displacement fields is presented. In two-dimensional problems a crack is modelled as a limiting case of two singular lines (with continuous displacements, but ... -
A computational model for progressive cracking in large dams due to the swelling of concrete
(1990-09)
Article
Open AccessThe paper presents a computational model for the analysis of large concrete gravity dams subjected to severe damage due to internal actions. It has been observed in several operating concrete dams that the combined effects ... -
An analysis of strong discontinuities induced by strain-softening in rate-independent inelastic solids
(Springer, 1993-09)
Article
Restricted access - publisher's policyKet qualitative features of solutions exhibiting strong discontinuities in rate-independent inelastic solids are identified and exploited in the design of a new class of finite element approximations. The analysis shows ... -
Seismic evaluation of concrete dams via continuum damage models
(Wiley, 1995-09)
Article
Open AccessIn this paper a general methodology for the analysis of large concrete dams subjected to seismic excitation is outlined. It is valid both for gravity dams (2D representation) and arch dams (3D representation). The method ... -
A rate-dependent isotropic damage model for the seismic analysis of concrete dams
(Wiley, 1996-09)
Article
Open AccessIn this paper a rate-dependent isotropic damage model developed for the numerical analysis of concrete dams subjected to seismic excitation is presented. The model is shown to incorporate two features essential for seismic ... -
A plasticity model for simulation of industrial powder compaction processes
(1996-08)
Article
Restricted access - publisher's policyA constitutive model, based on large strain plasticity, for simulation of industrial powder compaction processes is presented. The elastic response is stated in terms of a hyperelastic model based on a hookean elastic free ... -
A strain-based plastic viscous-damage model for massive concrete structures
(1998-05)
Article
Open AccessWithin the framework of continuum damage mechanics, a new constitutive damage model for massive concrete is presented, mainly intended for the seismic analysis of gravity and arch dams. Consistent with thermodynamic ... -
Thermo-chemo-mechanical model for concrete. II: damage and creep
(American Society of Civil Engineers, 1999-09)
Article
Open AccessIn this work a coupled thermo-chemo-mechanical model for the behavior of concrete at early ages is proposed. This paper presents the formulation and assessment of the mechanical aspects of the model. Short- and long-term ... -
Simulation of construction of RCC dams. II: stress and damage
(2000-09)
Article
Open AccessThe increasing number of roller compacted concrete (RCC) dams being built around the world demands accurate methodologies for the realistic short- and long-term evaluations of the risk of thermally induced cracking in these ...
