Abstract: Process zones in concrete have been under intensive investigations during the past several years. Techniques have successfully been used to detect and map the 2-D superficial process zone. However, recent 3-D numerical analysis indicate that the interior damage pattern is quite different from the pattern on the surface. The lack of detailed information concerning the 3-D process zone has hindered the development and validation of fracture mechanics theories based on the micromechanics of cracking.
