A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Comparison of 3D stress-strain concrete models
(2021)
The inelastic response of reinforced concrete buildings is strongly sensitive to the material stress-strain constitutive model adopted for concrete. This paper is a first step on an ongoing work to do a complete benchmark ...
An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials
(World Acad Sci, Eng & Tech-waset, 2007-01-01)
This work deals with the initial applications and formulation of an aniscitropic plastic-damage constitutive model proposed for non-linear analysis of reinforced concrete structures submitted to a loading with change of ...
A plastic damage approach for confined concrete
(Pergamon-Elsevier Science Ltd, 2005-10)
There are many situations in which it is necessary to increase the capacity of structures in use. This need maybe either for a change of use or because the structures have suffered some damage or have shown little resistance ...
Thermo-mechanic model for concrete exposed to elevated temperatures
(Elsevier, 2003-12)
A thermo-mechanical model for concrete subjected to high temperatures is presented in this paper. The model is based on a coupled plastic-damage model that has been extended to consider damage induced by high temperatures. ...

This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials

Zero-thickness interface constitutive theory for concrete self-healing effects
(Pergamon-Elsevier Science Ltd, 2017-07)
A damage-plasticity constitutive theory for zero-thickness interfaces is presented aimed at predicting time-dependent self-healing phenomena in concrete. The material model is based on fracture-energy concepts and accounts ...
