Abstract: The dissertation introduced first simple uniaxial compression test of concrete, and in the specimen under uniaxial compression of the breakage mode reinforced and improved. For tensile destruction and shear failure damage model, bring forward the corresponding calculation model and some model set up compressive strength and tensile strength of the interrelations with each other, analysis of compressive strength and much higher than the tensile strength.In addition, from different model, drew diagrams with Matlab software，analysis of the compressive strength and tensile strength of the intrinsic value of relations.Finally, model for the primary split breakage and that shear failure can be ignored, used the buckling theory and the theory of mutation analysis, and calculated the corresponding critical stress.
