Acoustic emission (AE) energy, instead of amplitude, associated with each of the event is used to estimate the fracture process zone (FPZ) size. A steep increase in the cumulative AE energy of the events with respect to time is correlated with the formation of FPZ. Based on the AE energy released du

In this paper we review experimental and field observations of the process zone, 4, size dependence in concrete and rock and suggest that a valid K,, test for such materials may require impractically large specimen sizes.

Three dimensional acoustic emission technique is applied to observe the phase of the fracture process zone of concrete which is created ahead of the crack tip and significantly influences the tension softening behaviour of concrete. The results show that the fracture process zone is already created
