TLDR
In this article, a constitutive model based on an internal variable-formulation of plasticity theory for the non-linear analysis of concrete is presented, which uses a new yield criterion which matches experimental data quite well and it accounts for both elastic and plastic stiffness degradations effects.About:

Plastic-Damage Model for Cyclic Loading of Concrete Structures
Jeeho Lee,Gregory L. Fenves +1 more
TL;DR: In this paper, a new plastic-damage model for concrete subjected to cyclic loading is developed using the concepts of fracture-energy-based damage and stiffness degradation in continuum damage mechanics.

Damage-plastic model for concrete failure
Peter Grassl,Milan Jirásek +1 more
TL;DR: In this article, a triaxial damage-plastic model for the failure of reinforced concrete columns is presented, where the plasticity part is based on the effective stress and the damage model is driven by the plastic strain.

An energy release rate-based plastic-damage model for concrete
Jian-Ying Wu,Jie Li,Rui Faria +2 more
TL;DR: In this article, a new plastic-damage constitutive model for concrete is proposed, where a tensile and a shear damage variable are adopted to describe the degradation of the macromechanical properties of concrete.

Finite element analysis of punching shear of concrete slabs using damaged plasticity model in ABAQUS
TL;DR: In this article, a nonlinear finite element analysis of reinforced concrete slab-column connections under static and pseudo-dynamic loadings was conducted to investigate their failures modes in terms of ultimate load and cracking patterns.
Journal ArticleDOI
A strain-based plastic viscous-damage model for massive concrete structures
TL;DR: In this article, a constitutive damage model for massive concrete is presented, mainly intended for the seismic analysis of gravity and arch dams, and an extension to account for the concrete strain-rate dependency, suitable for seismic analysis, is presented at the end.

Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.

Crack band theory for fracture of concrete
Zdeněk P. Bažant,Byung H. Oh +1 more
TL;DR: In this article, a fracture theory for a heterogenous aggregate material which exhibits a gradual strain-softening due to microcracking and contains aggregate pieces that are not necessarily small compared to structural dimensions is developed.

Behavior of Concrete Under Biaxial Stresses
Helmut B. Kupfer,Kurt H. Gerstle +1 more
TL;DR: In this paper, the results of an extensive series of tests of three types of concrete under biaxial loadings are used to develop stress-strain relations for concrete subjected to bialastic stress states, by means of a decomposition of the stresses and strains into their hydrostatic and deviatoric portions.

A fast incremental/iterative solution procedure that handles "snap-through"
TL;DR: In this article, a modified version of the Newton-Raphson method is proposed to overcome limit points in the finite element method with a fixed load level and a constraint equation.
