State of the Art on Constitutive Law of Continuum Concrete
By Ryoichi Sato
Concrete Journal,Vol.35,No.4,April 1997
- Synopsis
- This paper summarizes the previous studies on nonlinear behaviors of as well as constitutive models of continuum concrete.First,volume change,elasticity,plastic deformation,damage are conceptually illustrated relating to stress-strain relationship, including the confinement effect.Next,isotropic nonlinear elasticity models,orthtropic hypoelasticity models,elasto-plastic models and plasticity-damage models are explained systematically.
- Keywords:
- continuum concrete,constitutive law,nonliner elasticity,hypoelasticity,elasto-plasticity, plasticity-damage
