Damage constitutive model for concrete based on ideal undamaged state
The ideal stress-stain curve of concrete in uniaxial compression, which is not influenced by internal damage, was proposed according to the axial compressive experiments of concrete specimens with various surrounding pressures. The cyclic loading stress-stain relationship of concrete in the ideal state without damage was also studied. A concrete damage constitutive model was constructed based on the obtained ideal stress-stain curve. Comparisons of theoretical and experimental results show the validity of the proposed model.
