A general failure criterion for plain concrete (Q1087049)

A general three-dimensional failure criterion for plain concrete is proposed. The criterion has been formulated in terms of three normalized stress invariants and includes material parameters which may be obtained from experimental data. It has been shown that simple failure criteria such as the von Mises model, the Drucker-Prager model and the Bresler- Pister model are special cases of that proposed. The application of the criterion has been demonstrated by comparison with available experimental results. From the results of this comparison it can be seen that the criterion may be applied throughout the stress range from tensive stress to high compressive stress.
