摘要：

Concrete materials with a large number of micro-cracks were defined as inhomogeneous materials. And the mechanical properties of inhomogeneous materials were regarded as high-order deformation gradient dependent. Starting from the nonlocal thermodynamics theory and the hypothesis of total energy equivalence, the gradient-dependent nonlocal damage constitutive models of concrete under freeze-thaw action would be established in this paper.
