An experimental investigation into the failure of a particular concrete subjected to stress fields varying between biaxial compression, compression-compression-tension, and uniaxial tension is described. The results are compared with published data for related stress systems, and the shape of the failure surface in the compression-tension quadrants of stress space is shown to be of the simple hexagonal pyramid type.
