Abstract: The concrete is taken as the matrix,and the air holes produced in concrete as the inclusions.Based on the assumption of the D-P yield criterion for concrete matrix,the macroscopic D-P yield criterion for Air-entrained Concrete is finally derived by introducing the energy density supporting function and constructing the approximating function sequence to solve the non derivable problem on the boundary of the air hole for energy density supporting function.The decreasing influence of the air conte...

Key words: air-entrained concrete； energy density support function； effective friction coefficient；
