Abstract:
Through a meso-model, the nonlinearity and strain softening of the stress-strain relationship of concrete under compressive stress are explained from the perspective of damage, and the elastoplastic damage constitutive model of uniaxial compression concrete is established according to the isometric hypothesis and the basic principle of damage mechanics, which can derive the existing uniaxial compression constitutive relationship and reflect the stiffness degradation of concrete and the residual deformation after unloading. A class of damage function and plastic deformation empirical expression are proposed, and the stress-strain curve feature conditions and optimization algorithm are used to determine the model parameters. Compared with the results of the existing compression test, the results are in good agreement.
