Thermo-mechanic coupled damage simulation of idealized concrete material

Several special concrete structures are subjected to temperature cycling environment. Temperature will influence the physical and mechanical behaviours of material. As number loops increases, performance decrease. Two different multi-phase composite numerical models for herein introduced in this paper. Based on damage development evolution mortar interface transition zone under cycling, thermo-mechanic coupled multi-scale groups were simulated. Afterwards, failure process mode material uniaxial stress state was studied. It is found that within concentrates develop as increases. Finally, it verified remarkably internal distribution structures. The research findings present paper conducive improving properties aggregate by optimizing mix proportion.
