A New 3D Empirical Plastic and Damage Model for Simulating the Failure of Concrete Structure
Yan-tao Jiao,Bo Wang,Zhen-zhong Shen 한국콘크리트학회 2019 International Journal of Concrete Structures and M Vol.13 No.7
A new plastic–damage constitutive model based on the combination of damage mechanics and classical plastic theory was developed to simulate the failure of concrete. In order to explain different material behaviors of concrete under tensile and compressive loadings, the plastic yield criterion, the different kinematic hardening rule for tension and compressive and the isotropic flow rule were established in the effective stress space. Meanwhile, two different empirical damage evolution equations were adopted: one for compression and the other for tension. A multi-axial damage influence factor was also introduced to fully describe the anisotropic damage of concrete. Finally, the model response was compared with a wide range of experiment results. The results showed that the model could well describe the nonlinear behavior of concrete in a complex stress state.
