✦ Synopsis

The determination of the fracture process zone in concrete is a difficult experimental problem, because the resulting deformation is strongly localized and cannot be measured adequately by strain-gages or coarse moir4 techniques. The preliminary results of an experimental study of the strain field in notched and unnotched specimens indicate that the use of the high sensitivity moir4 interferometry allows a precise description of the fracture process zone and a more exact determination of the stress-strain relation for concrete in tension.

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

The fracture toughness so determined is shown not to depend on the size and geometry of the test specimen but on the m
