Digital image correlation analysis of interfacial debonding properties and fracture behavior in concrete
The use of digital image correlation (DIC) as a fracture mechanics tool is described for two projects currently underway. The goal of the first project is to examine the bond between carbon fiber reinforced polymers (CFRP) and concrete substrates. The second project involves the interfacial transition zone (ITZ) of plain concrete, and the softening and fracture behavior of this region. For both projects, DIC allows for precise measurement of the surface displacements of the deforming materials. The resulting strain data are higher in resolution than is possible with other experimental techniques. For both projects, the DIC results are being used to determine bond constitutive laws, which will be the basis for fracture mechanics studies of the materials.
