Abstract:It is possible to identify distinct levels of change in the behavior of concrete when subjected to multiaxial stress states. This identification is based on the hypothesis that the fracture mechanism is that of crack extension (due to branch initiation) followed by stable propagation which eventually becomes unstable. The variation of these levels in stress and strain space has been established and those which correspond to the start of the stable and unstable propagation processes provide the bases for lower and upper bound failure criteria suitable for practical structural design.
