Abstract: An incremental three-dimensional stress-strain relationship for concrete with induced anisotropy has been developed. The nonlinearity and path-dependency are modeled by expressing the elastic moduli ...

Abstract: An incremental three-dimensional constitutive relation for concrete has been developed. The linear anisotropic and path-dependent behavior is modeled by updating the stiffness matrix at each load ...

Abstract: The salient features and concepts of a model developed in Part I of this paper are reviewed. The model is extended to include dilatancy and shear compaction which are determined from uniaxial ...

Abstract: The salient features and concepts of a model developed recently are reviewed. The parameters of the model are the peak compressive stress of concrete, initial elastic modulus, and tangential Poisson's ratio. The peak stress ...
