Abstract
Design of yield criterion for concrete using the deviatoric and meridional section shape functions is presented. For the deviatoric section, Podgórski type shape functions are applied and discussed, while for the meridians Cassini’s oval is considered. Derivation of the shape functions with determination of free parameters using typical experimental test is shown. Comparison with empirical data for concrete is given. The proposed approach is a quite general tool in development of failure criteria for frictional and brittle materials.
