Abstract:Based on the damage mechanics and Ottosen failure model, a frost damage failure model is established in which elastic modulus and Possion ratio under damage are the damage variables. And based on Ottosen theory, a frost damage constitutive model is established and all these will be useful to the development of finite element programme. The test of the constitutive model by the experimental data shows that it is accurate comparatively.
Keywords:concrete  frost damage  constitutive model  failure model
