The results showed that different materials correspond to different strength theories.
The Application of the Intensity Theory Equation-(3) applies not only to brittle materials, but also to ,ie, some plastic material When λ =1.At this time equation-(3) is the twinτ2 Yield Criterion.
Compared with some concrete experimental data, the twin shearing strength theory of two parameters is feasible in the strength analysis of concrete materials .So it improves and enriches the concrete material strength theory.
