- A yield condition for concrete under moderate hydrostatic pressure is proposed as a nineparameter extension of the Lubliner yield criterion. The modification is introduced to both meridional and deviatoric cross-sections. Singularities are eliminated by means of a regularisation parameter of a clear geometrical interpretation. Calibration is carried out resulting in analytical formulae for the parameters depending on experimental data for five characteristic tests. A comparison with experimental data available in literature is drawn, showing consistency between the yield criterion and the test results. Convexity requirements for the proposed function are determined, leading to limitations on the input data.
